Question

Translate the following statements into chemical equation and then balance the equation (a) Hydrogen sulphide gas burns in air to give water and sulphur dioxide

Answer 1

hi mate answer follows

these are the chemical name we have to know  for  framing equation

Hydrogen sulphide gas= h2s here 2 comes below the hydrogen

air= 02 here 2 comes below the oxygen

water= h20  here 2 comes below the  hydrogen

sulphur dioxide= SO2  here 2 comes below the oxygen

chemical equations which is unbalanced

Hydrogen sulphide gas burns in air to give water and sulphur dioxide

h2s+o2----------> h20+so2

balanced equation

we have to put 2 before h2s ,3 before o2 these are i n reactants side or rhs

we have to  put 2 before h2o,  2 before so2

2h2s+3o2--------------------------> 2h2o+2so2

we can check the no.of atom

name               rhs             lhs

hydrogen         4                  4

sulphur              2               2  

oxygen           6                     2+4=6

hope this helps u

Answer 2

Answer:

2H2S+3O2----->2H2O+2SO2
