Balance the following equations

3. ___ GaBr3 + ___ Na2SO3 -> ___ Ga2(SO3)3 + ___ NaBr

4. ___ SnO + ___ NF3 -> ___ SnF2 + ___ N2O3

Answer 1

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

#2. 3SnO + 2NF₃ → 3SnF₂ + N₂O₃

Step-by-step 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
