Answer 1

Answer:

$Mg(s) + HCl(aq) \rightarrow MgCl_2(aq) + H_2(g)$

$MgO(s) + HCl(aq) \rightarrow MgCl_2(aq) + H_2O(l)$

Explanation:

When Mg reacts with HCl, magnesium chloride and hydrogen is formed. Mg is an active element and displaces hydrogen from HCl. So, this is a type of single displacement reaction.

$Mg(s) + HCl(aq) \rightarrow MgCl_2(aq) + H_2(g)$

When magnesium oxide (MgO) reacts with HCl, magnesium chloride and water is formed. This reaction is a type of neutralization reaction. MgO is a water insoluble base and HCl is acid. So. in this reaction, acid reacts with base to form salt $MgCl_2$

$MgO(s) + HCl(aq) \rightarrow MgCl_2(aq) + H_2O(l)$
