1. Write the balanced chemical equation for the following.

Hydrogen(g) + Chlorine(g) → Hydrogen chloride(g)

\(H_2\)(g) + \(Cl_2\)(g) → \(2HCl\)(g)
(N_2\)(g) + \(Cl_2\)(g) → \(2HCl\)(g)
\(H_2\)(g) + \(Cl_2\)(g) → \(2HBr\)(g)
\(H_2\)(g) + \(Cl_2\)(g) → \(2OCl\)(g)
\(O_2\)(g) + \(Cl_2\)(g) → \(2HCl\)(g)

2. Identify the type of the following reaction.

Hydrogen(g) + Chlorine(g) → Hydrogen chloride(g)
