Hydrobromic acid is added to a solution of lead(II) nitrate. Predict the products, and write a balanced equation for this reaction. Phases are not necessary.

2HBr + Pb(NO₃)₂ → PbBr₂ + 2HNO₃

Explanation:

Hydrobromic acid (HBr), reacts with lead (II) nitrate (Pb(NO₃)₂) producing Lead(II) bromide (PbBr₂) and nitric acid (HNO₃). The reaction is:

HBr + Pb(NO₃)₂ → PbBr₂ + HNO₃

This reaction is unbalanced. You can see in products 2 Bromides but in reactants just 1. And in reactants 2 NO₃ but as product just 1. Thus, you can balance the equation, thus:

2HBr + Pb(NO₃)₂ → PbBr₂ + 2HNO₃

And this equation is the answer of your question!
