Question

Mg + HCl - Mg SO4 + H2O

Answer 1

Ответ:

MgSO4·7H2O + 2HCl = MgCl2 + H2SO4 + 7H2O

Answer 2

The chemical equation you provided is not balanced and seems to contain an error. It appears to be a combination of two different reactions involving magnesium (Mg) and hydrochloric acid (HCl), as well as magnesium sulfate (MgSO4) and water (H2O). To provide a correct balanced equation, I will assume you meant two separate reactions:

1. Reaction between magnesium and hydrochloric acid: Mg + 2HCl → MgCl2 + H2

2. Reaction between magnesium sulfate and water (hydration): MgSO4 + 7H2O → MgSO4 · 7H2O

Please note that the second reaction is a hydration reaction and not a chemical reaction in the same sense as the first one. The compound formed in the second reaction is a hydrated form of magnesium sulfate (MgSO4 · 7H2O). If you meant something else or have additional information, please let me know!
