Question

2. Given the unbalanced equation:

Na(s) +
H2O(1) -
NaOH(aq) +
Н.
When this equation is balanced, the reactant Na(s) and the product NaOH(aq) both have coefficients of
1) 1
2) 2
3) 3
4) 4

Answer 1

2 Na + 2 H2O → 2 NaOH + H2 (balanced equation)
The answer would be 2, since 2 in the coefficient of both Na and NaOH
