<p>le chatelliers question??</p>
<p>increase temp?</p>
<p>thanks scareya!</p>
<p>I forgot the equation for lechatelliers principle
all i remember is that the reaction was endothermic & if you increase temperature - the reaction goes forward and create more products</p>
<p>i forgot what the question asked</p>
<p>answer for that one was decreasing something and increasing something. i think</p>
<p>hmm...thats interesting - i remember that question & that choice - but i chose A - but i forgot what that was</p>
<p>was the question what would increase the concentration of the reactants?</p>
<p>i thought it was increse the products.. </p>
<p>i think it was add heat</p>
<p>the le chattiers one?</p>
<p>it was how to make more CO2 (which was a product, which is why I cancelled out decreasing the volume, cause there wer 4 moles on the right, 2 moles on the left)</p>
<p>reaction was endothermic - increase temp and it would shift right.</p>
<p>the decreasing one and increasing other would cause it to shift left though, cause you were decreasing one reactant and increasing another.</p>
<p>It was A - Increasing temp. (I think)</p>
<p>I put CaBr2 for ionic and covalent.</p>
<p>I put mercury (lowest C)</p>
<p>Yes, It was increase the reactants, and decrease the product that you want more of.</p>
<p>Higher temp favors reactants if its exothermic, this reaction was endothermic.</p>
<p>it was increasing the reactant, wasn't it?</p>
<p>Evilbooya, I'm guessing Cs and Rb aren't seen as much simply because H, Li, Na, and K are much more common.</p>
<p>i think aneezah is correct</p>
<p>Hmm...I don't remember. Can someone who remembers post what the question asked...and the reaction?</p>
<p>EDIT: so many posts before I made this</p>
<p>I guess the answer is A - increase temp</p>
<p>how could CaBr2 include a covalent bond?</p>
<p>Cs is definitely the most reactive.
I saw a video on this one in school.
The container blew up when they added Cs..hehe</p>
<p>CaBr2 does not include a covalent bond </p>
<p>I think the answer was a polyatomic ion that ionically bonds to something...I forgot the answer</p>
<p>I think reactivity decreases as you go down the group...b/c the atomic radius increases.</p>
<p>Piece of cake.</p>
<p>oh I just thought Br-Br would be covalent.. guess not =)</p>
<p>Br2 is covalent, but CaBr2 is not</p>
<p>Br = -1
Ca = +2</p>
<p>You need to Br's to ionically bond with the 1 Ca. If you don't get my explanation...IM/PM me.</p>
<p>Does CO2 produce slightly acidic properties in water?</p>
<p>yeah it forms carbonic acid</p>
