Use the equation to answer the question. 4NaCl + 2SO2 + _____H2O + _____O2 → _____Na2SO4 + 4HCl Which numbers balance this equation? (1 point)
1.) 2, 1, 2
2.) 1, 2, 2
3.) 1, 2, 4
4.) 2, 1, 4
The balanced equation using the Law of Conservation of Mass is:
4NaCl + 2SO2 + 4H2O + 3O2 → 2Na2SO4 + 4HCl
None of the provided answer choices match the balanced equation. However, option 4.) 2, 1, 4 is the closest in terms of the number of oxygen atoms on each side of the equation (4 on the left and 4 on the right).
