BRAINLIESTTT ASAP!! PLEASE HELP ME :)

Answer 1

_____________________________

Students should balance the chemical equation to obey the rules of laws of conservation of mass.

As we know that,

Laws of conservation of mass is used for balancing this chemical equation.

2H2S(g) + 3O2(g) → 2H2O(l) + 2SO2(g)

Here,

Left Hand Side = Right Hand Side

4 atoms of H = 4 atoms of H

2 atoms of S = 2 atoms of S

6 atoms of O = 6 atoms of O

So, by the help of laws of conservation of mass, we can balance any chemical equation.

Answer 2

2H2S + 3O2 → H2O + SO2

We have 4 H on the left and 2 on the right

2 S on the left and 1 on the right

6 O on the left and 3 on the right

We need to multiply everything on the right  by 2

Add a coefficient 2 before H2O and a 2 before SO2.

2H2S + 3O2 → 2H2O + 2SO2

4H  4H

2S = 2S

6O =2O
