Answer:
CN⁻(aq) + H⁺(aq) → HCN(l)
Explanation:
The reactants are aqueous solutions:
NaCN(aq) and HBr(aq)
When you mix these compounds you make pure HCN (l)
The molecular equation is:
NaCN(aq) + HBr(aq) → NaBr(aq) + HCN(l)
When you dissociate the reactants, you have:
Na⁺(aq) +CN⁻(aq) + H⁺(aq) + Br⁻(aq) → Na⁺(aq) + Br⁻(aq) + HCN(l)
Sodium bromide, it is a salt, that can also be dissociated in the solution
To make, the net ionic equation you remove the repeated ions
CN⁻(aq) + H⁺(aq) → HCN(l)
