2020-2021 Review HW For Balancing, Types, Predicting And Energy Change Of Chemical Reactions

• If the reaction does not occur, please give a one sentence explanation of why it does not.
• If the reaction does occur, please give a balanced complete chemical reaction including phases of reactants and products. Then show all work to determine the net ionic reaction.

• If the reaction does not occur, determine the potential products and phases and show all work to get the net ionic reaction to show that the reaction does not occur (i.e. everything crosses out because all species are spectator ions).
• If the reaction does occur, please give a balanced complete chemical reaction including phases of reactants and products. Then show all work to determine the net ionic reaction.

1. Na₂(SO₄)_{1 (aq)} + K₁(NO₃)_{1 (aq)} -->











2. K₂(CO₃) _{1 (aq)} + Ba₁Cl_{2 (aq)} --->











3.Ba_(s) + Al₂(SO₄)_{3 (aq)} -->
