Question

How to balance 2hcl+na2s=h2s+2nacl

Answer 1

Dear it is already balanced see it carefully

2 HCl + Na2S = H2S + 2 NaCl

H=2 , Cl=2, Na=2 , S=1

on other side H=2 , S=1 , Na=2 , Cl=2

this equation is already balanced

Answer 2

hello friends ,

given equation :-

2 HCl + Na2S =  H2S + 2 NaCl

now ,

no. of atoms : in reactants : in product

1. hydrogen : 2  :  2

2. chlorine :  2   :  2

3. sodium  :   2  :  2

4. sulphur  :  1    :  1

so , from above observation we can conclude that the given equation is a balanced equation .
