Question

А)In +H2So4→...б)Cu + HCe→...в) Hg + H2So4→...​

Answer 1

Ответ:

2In + 3H2SO4 → In2(SO4)3 + 3H2

Cu + 2HCl → CuCl2 + H2

Hg + 2H2SO4 → HgSO4 + 2H2O + SO2

Объяснение:

Answer 2

А) When sulfuric acid (H2SO4) reacts with water (H2O), it undergoes ionization, producing hydronium ions (H3O+) and sulfate ions (SO4^2-):

H2SO4 + H2O → H3O+ + HSO4^-

So, the reaction can be represented as the formation of hydronium ions and bisulfate ions.

Б) When copper (Cu) reacts with hydrogen chloride (HCl), it forms copper chloride (CuCl2) and hydrogen gas (H2):

Cu + 2HCl → CuCl2 + H2

So, the reaction is the formation of copper chloride and hydrogen gas.

В) When mercury (Hg) reacts with sulfuric acid (H2SO4), it produces mercuric sulfate (HgSO4) and hydrogen gas (H2):

Hg + H2SO4 → HgSO4 + H2

So, the reaction is the formation of mercuric sulfate and hydrogen gas.
