Question

acetic acid + copper
CH3COOH + Cu -> CuCH3COOH?

hyrdrogen peroxide (catalyzed by manganese dioxide)
H2)2 -(MnO2)> H2 + O2?

thanks in advance

Answer 1

1. no. Cu is below H in the activity series and there will be no reaction between Cu and acetic acid.
2. looks ok to me.

Answer 2

for number one, do you mean it is impossible for copper to be after the acid?

Answer 3

I mean that Cu and CH3COOH do not react. For all practical purposes, they sit there and look at each other. If you put copper shavings in acetic acid and leave it for several days, you will get a small amount of green copper acetate but the amount is small and it takes some time to get even a little. Compare this with a metal, such as zinc and the reaction with an acid; there are volumes and volumes of H2 gas formed.
