I need help! please! A chemical equation is shown below.
HgS + O2 → HgO + SO2
What are the coefficients that should be added to balance this equation? Use complete sentences to explain your answer. Explain how this chemical reaction demonstrates the conservation of mass.

1. 2 HgS + 3 O2 -> 2 HgO + 2 SO2

2. The law of conservation of mass states that in a closed system mass cannot be created or destroyed. Therefore, in this chemical reaction, the total mass at the start of the reaction should equal the total mass at the end of the reaction. You can see that there is displacement hence the weight stays the same. Nope this helps!
