balance the following equations

3. gabr3 + na2so3 -> ga2(so3)3 + nabr

4. sno + nf3 -> snf2 + n2o3

#1.  2GaBr₃ + 3Na₂SO₃ → Ga₂(SO₃)₃ + 6NaBr

#2. 3SnO + 2NF₃ → 3SnF₂ + N₂O₃

Explanation:Balancing chemical equations involves  putting appropriate coefficients on the products and reactants to ensure the number of atoms of each element are equal on either side of the equation.Balancing chemical equations makes them obey the law of conservation of mass in chemical equations.In this case; to balance the first equation, we put coefficients 2, 3, 1 and 6 on the equation.That is, the balanced equation will be;

2GaBr₃ + 3Na₂SO₃ → Ga₂(SO₃)₃ + 6NaBr

To balance the second equation, we put coefficients 3, 2, 3 and 1 respectively.Thus, the balanced chemical equation will be;

3SnO + 2NF₃ → 3SnF₂ + N₂O₃

Ithink the answer is d.
