q.1 write the equation for the reaction of magnesium with hcl.
mg + 2hcl -> mgcl₂ + h₂
q.2 based on the above equation, how many moles of hcl are reacted with each
mole of mg?

Explanation:

Step1: Analyze the balanced chemical equation

The balanced equation for the reaction of magnesium (\(Mg\)) with hydrochloric acid (\(HCl\)) is \(Mg + 2HCl
ightarrow MgCl_{2}+H_{2}\).

Step2: Determine the mole ratio

From the balanced equation, the coefficient of \(Mg\) is \(1\) and the coefficient of \(HCl\) is \(2\). The mole ratio of \(HCl\) to \(Mg\) is \(\frac{n_{HCl}}{n_{Mg}}=\frac{2}{1}\).

Answer:

\(2\) moles of \(HCl\) are reacted with each mole of \(Mg\).
