Question

H2SO4+Zn ОВР ________________________

Answer 1

Zn + H2SO4 = ZnSO4 + H2

Zn(0)-2e = Zn(+2)   1    в-ль

2H(+) +2e = H2(0)  1    ок-ль

Answer 2

The chemical equation provided is incomplete, so I am assuming that you are asking for the balanced equation for the reaction between sulfuric acid (H2SO4) and zinc (Zn) to produce hydrogen gas (H2) and zinc sulfate (ZnSO4) as the products.

The balanced chemical equation for the reaction is:

H2SO4 + Zn → ZnSO4 + H2

This equation shows that one molecule of sulfuric acid reacts with one atom of zinc to produce one molecule of hydrogen gas and one molecule of zinc sulfate.

In terms of the reaction type, this is an example of a single displacement or single replacement reaction, where one element or ion replaces another element in a compound. In this case, the zinc atoms replace the hydrogen ions in sulfuric acid to produce hydrogen gas and zinc sulfate.
