a. Solid K has an electron configuration of [Ar]4s1, so it has an unpaired electron. This allows electric current to flow through the structure. KNO3 does not have an unpaired electron, so no electricity flow in.<br />
b. SbCl3 has measurable dipole movement because the molecule is polar, so there is attraction between SbCl3 and other polar molecules. SbCl5 is non-polar, so there is no dipole interaction occurring.<br />

c. Both of these molecules are non-polar, but CBr4 has the higher boiling point because it has more electrons, and therefore it is harder to separate.<br />
d. NaI is polar, so it is easy for it to bond with other molecules in a solution. I2 is non-polar and symmetrical, so it is harder to separate.<br />
f. Sulfur has an expanded octet (12 electrons) because it is in the third energy level, so there are more options for bonding. Oxygen is only in the second energy level, and therefore is restricted to 8 electrons.Unknownnoreply@blogger.com3tag:blogger.com,1999:blog-6042599738129438159.post-73892351345914407662011-11-09T19:13:00.000-08:002011-11-13T11:11:38.911-08:00Trimester One Exam Review - Question 26 and 27 (HUZZAH!)<u><span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif;">Electron Configurations</span></u><br />

Properties)!<b><span class="Apple-style-span" style="font-size: large;">Physical Properties </span></b><br />
<i>Each of the following properties listed are physical properties because I did not change the chemical ID of the substance</i> <i>to discover the facts.</i><br />
<br />
<u>Color</u><br />
To begin, I decided I would try to determine the color of said Epsom Salts. It was quite the difficult task. It involved opening the carton and looking at it. Very tough. But after careful consideration that looked a lot like this:<br />
<div class="separator" style="clear: both; text-align: center;"><a href="http://1.bp.blogspot.com/-FIWqwkaugUk/TnZKrX8wZVI/AAAAAAAAAEA/ik34SKjnlHo/s1600/color.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="238" src="http://1.bp.blogspot.com/-FIWqwkaugUk/TnZKrX8wZVI/AAAAAAAAAEA/ik34SKjnlHo/s320/color.JPG" width="320" /></a></div><div class="separator" style="clear: both; text-align: left;"><br />
</div><div class="separator" style="clear: both; text-align: left;">I realized that epsom salt was, in fact, white. It also did have a transparent quality as well. Neat-o. </div><div class="separator" style="clear: both; text-align: left;"><br />
</div><div class="separator" style="clear: both; text-align: left;"><u>Phase</u></div><div class="separator" style="clear: both; text-align: left;">Next, I needed to discern the phase of the salt. After centuries of this:</div><div class="separator" style="clear: both; text-align: center;"><a href="http://3.bp.blogspot.com/-axYwToJVXvI/TnZeOBWPLlI/AAAAAAAAAEE/_G5CNvsu8N4/s1600/phase.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="320" src="http://3.bp.blogspot.com/-axYwToJVXvI/TnZeOBWPLlI/AAAAAAAAAEE/_G5CNvsu8N4/s320/phase.jpg" width="240" /></a></div><div class="separator" style="clear: both; text-align: center;"><br />
</div><div class="separator" style="clear: both; text-align: left;">I came to the conclusion that it was a solid (as it was defined by having both a definitive shape and volume).</div><div class="separator" style="clear: both; text-align: left;"><br />
</div><div class="separator" style="clear: both; text-align: left;"><u>Malleable</u></div><div class="separator" style="clear: both; text-align: left;">Malleability is the ability to be hammered into thin sheets. So naturally I picked this property to try because it sounded like fun. This is what it looked like (be afraid):</div><div class="separator" style="clear: both; text-align: center;"><a href="http://4.bp.blogspot.com/-j010icXVJ9w/TnZfQA3YfwI/AAAAAAAAAEY/ZIdFuguD3Tw/s1600/malleable.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="320" src="http://4.bp.blogspot.com/-j010icXVJ9w/TnZfQA3YfwI/AAAAAAAAAEY/ZIdFuguD3Tw/s320/malleable.jpg" width="240" /></a></div><div class="separator" style="clear: both; text-align: center;"><br />
</div><div class="separator" style="clear: both; text-align: left;">But much to my dismay (and my mother's delight), epsom salt is not malleable. It just broke down into smaller grains, like so:</div><div class="separator" style="clear: both; text-align: center;"><a href="http://2.bp.blogspot.com/-iQb5KooD3mo/TnZfc6M6CBI/AAAAAAAAAEc/OGeb-Fo4xh4/s1600/malleable2.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="240" src="http://2.bp.blogspot.com/-iQb5KooD3mo/TnZfc6M6CBI/AAAAAAAAAEc/OGeb-Fo4xh4/s320/malleable2.JPG" width="320" /></a></div><div class="separator" style="clear: both; text-align: center;"><br />
</div><div class="separator" style="clear: both; text-align: left;">Bummer. So it's safe to say that malleability is not a physical property of epsom salt.</div><div class="separator" style="clear: both; text-align: left;"><br />
</div><div class="separator" style="clear: both; text-align: left;"><u>Solubility</u></div><div class="separator" style="clear: both; text-align: left;">AH! One of my favorites. I put about a half cup of the salt into about a half cup of water. Interestingly enough, the result was this:</div><div class="separator" style="clear: both; text-align: center;"><a href="http://4.bp.blogspot.com/-u1d1uuf94_c/TnZfzaW3vaI/AAAAAAAAAEk/SCtwIWadEWQ/s1600/sollubility2.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="320" src="http://4.bp.blogspot.com/-u1d1uuf94_c/TnZfzaW3vaI/AAAAAAAAAEk/SCtwIWadEWQ/s320/sollubility2.jpg" width="240" /></a></div><div class="separator" style="clear: both; text-align: center;"><br />
</div><div class="separator" style="clear: both; text-align: left;">As we can see, after stirring the mixture, it separated. Upon closer inspection, we can see that the crystals have lost their milky hue (which is now tainting the water). The compound that is epsom salts (magnesium sulfate) does not completely dissolve in water. In a later property, I shall explain what has happened.</div><div class="separator" style="clear: both; text-align: left;"><br />
</div><div class="separator" style="clear: both; text-align: left;"><u>Taste</u></div><div class="separator" style="clear: both; text-align: left;">Oh, God. This one was NASTY. Every tried tasting magnesium sulfate? I do NOT recommend it. So after letting one crystal dissolve on my tongue and was disgusted, I delegated the task:</div><div class="separator" style="clear: both; text-align: center;"><a href="http://1.bp.blogspot.com/-KOE-RbR_r54/TnZf-E6uFNI/AAAAAAAAAEo/_ZU1os1t07A/s1600/taste.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="320" src="http://1.bp.blogspot.com/-KOE-RbR_r54/TnZf-E6uFNI/AAAAAAAAAEo/_ZU1os1t07A/s320/taste.JPG" width="248" /></a></div><div class="separator" style="clear: both; text-align: center;"><span class="Apple-style-span" style="font-size: x-small;"><i>The Original Chemistry Cat</i></span></div><div class="separator" style="clear: both; text-align: center;"><br />
</div><div class="separator" style="clear: both; text-align: left;">She was not impressed. The salt had a bitter taste. It was gross. But I digress. I just need to communicate how positively revolting it was. </div><div class="separator" style="clear: both; text-align: left;"><br />
</div><div class="separator" style="clear: both; text-align: left;"><br />
</div><div class="separator" style="clear: both; text-align: left;"><b><span class="Apple-style-span" style="font-size: large;">Chemical Properties</span></b></div><div class="separator" style="clear: both; text-align: left;"><i>Each of the following properties listed are chemical properties because I did have to change the chemical ID of the substance</i> <i>to discover the facts.</i></div><div class="separator" style="clear: both; text-align: left;"><i><br />
</i></div><div class="separator" style="clear: both; text-align: left;"><u>Flammability</u></div><div class="separator" style="clear: both; text-align: left;">One of my personal favorites. This required safety goggles and adult supervision (two of my least favorite things... the sacrifices I make for science). I dumped a pile of the salt on the ground and stuck a match. It was just as neanderthal as it sounds, and it looked like this:</div><div class="separator" style="clear: both; text-align: center;"><a href="http://1.bp.blogspot.com/-xWwyYsQApcI/TnZwjSjzFfI/AAAAAAAAAFU/bFxIvbFNi4g/s1600/flammable.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="240" src="http://1.bp.blogspot.com/-xWwyYsQApcI/TnZwjSjzFfI/AAAAAAAAAFU/bFxIvbFNi4g/s320/flammable.JPG" width="320" /></a></div><div class="separator" style="clear: both; text-align: center;"><span class="Apple-style-span" style="font-size: x-small;"><i>Pretty Snazzy, no?</i></span></div><div class="separator" style="clear: both; text-align: center;"><span class="Apple-style-span" style="font-size: x-small;"><i><br />
</i></span></div><div class="separator" style="clear: both; text-align: left;">Despite the annoying wind that kept blowing out the flame, I managed to block it for long enough to know that no amount of prodding will end in a bonfire. Disappointed, I blew out the match and shuffled back inside, where I discovered five mosquito bites. Not only did I not get the explosion of inferno that I dreamed of, I had to set back my schedule to treat my wounds. Epsom salt is not flammable... darn.</div><div class="separator" style="clear: both; text-align: left;"><u><br />
Reactivity of Acid</u></div><div class="separator" style="clear: both; text-align: left;">At the request of our teacher, we were not allowed to break open a battery and pour it on the substance. But I made do with vinegar. So I put a half cup of epsom salt in a cup and poured in enough vinegar to drown a bat. Again, no furious explosion, nothing. Sad, really. It just did this:</div><div class="separator" style="clear: both; text-align: center;"></div><div class="separator" style="clear: both; text-align: center;"><a href="http://3.bp.blogspot.com/-WEpa7_MkqkY/TnZv7IiAkgI/AAAAAAAAAFI/dlx4fhv-sYE/s1600/acid2.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="300" src="http://3.bp.blogspot.com/-WEpa7_MkqkY/TnZv7IiAkgI/AAAAAAAAAFI/dlx4fhv-sYE/s400/acid2.JPG" width="400" /></a></div><div class="separator" style="clear: both; text-align: center;"><span class="Apple-style-span" style="font-size: x-small;"><i>Big, Fat, NOTHING!</i></span></div><div class="separator" style="clear: both; text-align: center;"><span class="Apple-style-span" style="font-size: x-small;"><i><br />
</i></span></div><div class="separator" style="clear: both; text-align: left;">So it is safe to say that epsom salt does NOT react with acid. So what does it do? Which brings me to...</div><div class="separator" style="clear: both; text-align: left;"><br />
</div><div class="separator" style="clear: both; text-align: left;"><u>The pH Balance</u></div><div class="separator" style="clear: both; text-align: left;">Not exactly the most exciting, but whatever. Since I didn't have any means to conduct this test on my own, I used the magical world wide web. According to W Chemicals Online <span class="Apple-style-span" style="font-size: xx-small;">(http://w-chemicals.com/properties-of-magnesium-sulfate/)</span> the pH balance of magnesium sulfate is 6.0. Neither an acid or a base, right in the middle. The pH balance of a solution is the measure of how much hydrogen is in a given substance. In order to gain this information, we must change the chemical ID of the substance, thus it is a chemical property.</div><div class="separator" style="clear: both; text-align: left;"><br />
</div><div class="separator" style="clear: both; text-align: left;"><u>Upon Heating</u></div><div class="separator" style="clear: both; text-align: left;">According to W Chemicals Online <span class="Apple-style-span" style="font-size: xx-small;">(http://w-chemicals.com/properties-of-magnesium-sulfate/)</span>, when magnesium sulfate is heated at over 250 degrees Celsius, epsom salt is broken down into magnesium oxide. Which changes the chemical ID of the substance. Which makes it a chemical property. TADAA!</div><div class="separator" style="clear: both; text-align: left;"><br />
</div><div class="separator" style="clear: both; text-align: left;"><u>Transfer of Energy</u></div><div class="separator" style="clear: both; text-align: left;">In my personal opinion, this is the coolest. First, I put a half cup of lukewarm water in a jar. My dad happened to have a temperature probe. The water was 26.6 degrees Celsius.</div><div class="separator" style="clear: both; text-align: center;"><a href="http://4.bp.blogspot.com/-ayF_KCd8V6w/TnZ2048zw2I/AAAAAAAAAFY/bBspY8ke3IQ/s1600/energy.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="320" src="http://4.bp.blogspot.com/-ayF_KCd8V6w/TnZ2048zw2I/AAAAAAAAAFY/bBspY8ke3IQ/s320/energy.jpg" width="240" /></a></div><div class="separator" style="clear: both; text-align: left;"><br />
</div><div class="separator" style="clear: both; text-align: left;">After, I added a half cup of epsom salt. I stirred it until the water had broken the substance down into two ions: magnesium and sulfate (thus changing the chemical ID). The energy it took to make this change lowered the temperature. The second measurement of heat (after the salt was added) was 22.2 degrees Celsius. This was an endothermic reaction. Cool, no?</div><div class="separator" style="clear: both; text-align: center;"><a href="http://2.bp.blogspot.com/-1T4GtMLooPQ/TnZ3_cPVZzI/AAAAAAAAAFc/JrgBuxswulk/s1600/energy1.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="320" src="http://2.bp.blogspot.com/-1T4GtMLooPQ/TnZ3_cPVZzI/AAAAAAAAAFc/JrgBuxswulk/s320/energy1.jpg" width="240" /></a></div><div class="separator" style="clear: both; text-align: center;"><br />
