Question

Could you pls help MEEEE??

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.

Answer 1

Answer:

Explanation:

2 S-II - 12 e- → 2 SIV (oxidation)

6 O0 + 12 e- → 6 O-II (reduction)

2 HgS (s) + 3 O2 (g) → 2 HgO (s) + 2 SO2 (aq)

This is an oxidation-reduction (redox) reaction:

2 S-II - 12 e- → 2 SIV (oxidation)

6 O0 + 12 e- → 6 O-II (reduction)

HgS is a reducing agent, O2 is an oxidizing agent.

Answer 2

The coefficients added to Hg S, 02, Hg O and SO2 to balance this equation are 2, 3, 3,2 respectively.

What do you mean by balanced equation ?

A balanced equation has the same number of atoms on the reactant and product sides for each element involved in the reaction.

The balanced equation for this reaction is:

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

This chemical reaction demonstrates the conservation of mass as the same number of atoms of each element appear on either side of the equation.

This means that the total mass of atoms on the reactant side of the equation will equal the total mass of atoms on the product side of the equation.

Therefore the coefficients added to Hg S, 02, Hg O and SO2 to balance this equation are 2, 3, 3,2 respectively.
