Question

1. Balance the following chemical equations. 1. Na + HO NaOH + H₂ 2. NaOH + H2SO, Na So HO 3. Mg + I Mg2​

Answer 1

Answer:

1. 2Na + 2H2O - 2NaOH + H2

Explanation:

2Na + 2H2O - 2NaOH + H2

reactant side Product side

Na - 1 x 2 = 2 Na - 1 x 2 = 2

O - 1 x 2 = 2 O - 1 x 2 = 2

H - 2 x 2 = 4 H - 2 + 2 = 4
