aight cool
I think the curve will be around -4/5
Everyone always says it’s like 2-3, but there’s no way the percentile would be like 92% if it was so tight

@ros12122
20 x 2.5 = 50
50 + 4.127 = 54
Adding copper to water or something. The question didn’t mention sig figs, but from the answer choices, you has to use them.

@grindboy I thought the second statement was catalysts don’t change the mechanism.

Ooooooo, might have been actually… Either way, they don’t change the mechanism right?

@teenagecrime - Forgot the question, but either pH=7 or equal moles at the equivalence point.

@alldaboston Don’t think so, but I put TT

for the catalyst ? I think I put TTCe, but what was the one about the most oxydation states?

@teenagecrime equal moles

Changed my answer to that last minute tears

what was color? was it Na or Strontium? both are yellow, arent they?

@Xiangestinium It was Na. Strontium burns bright red.

The radiation one asking for a graph, I assume it was looking for a half life graph, right, and was it the negative curved one?

I put TT but no CE
cause they change the mechanism by offering an alternative pathway? that was my reasoning

@alldaboston Yup

i said TF because catalysts dont change mech, they don’t affect the reaction in terms of reactants and products

What was the answer to the last question about isomers?

@Xiangestinium If you write out the equation, they technically are a reactant and product, but I think I must have read the question wrong -.-

@Xiangestinium but the mechanism is the steps of the reaction. It doesn’t change the overall net equation but it does change the intermediate steps

(edit: typo, cause I’m that kind of person :P)

What do you think the curve will be? If I got a raw score of 80 what is that…like a 780 or 790?

@Xebaism well the catalyst isnt actually reacted… It enters and leaves as the same compound

@kgsoccer08 Yup, pretty much that.
