Explanation:
Sr(OH) 2 = Strontium Hydroxide
The numbers that balance the following equation: 4NaCl + 2SO2 + H2O + O2 → Na2SO4 + 4HCl is 2, 1, 2.
BALANCING EQUATION:
- Balancing a chemical equation means to make sure that the number of atoms of each element on both sides of the equation are equal.
- According to this question, the following chemical reaction are given: 4NaCl + 2SO2 + H2O + O2 → Na2SO4 + 4HCl
- Some of the coefficients (numbers) have been placed there while some are missing. The equation that includes the missing coefficients (numbers) to balance the equation is:
4NaCl + 2SO2 + 2H2O + O2 → 2Na2SO4 + 4HCl
