Question

How can be balance a chemical equation step by step explanation.​

Answer 1

Answer:

for balancing a chemical chemical equation the mass of reactants

must be equal on both sides of the equation and the atoms are also equal on both sides of the equation

for example :

2Na + Cl2 = 2NaCl , in left hand side the atoms of na=2 and on right hand side the atoms of na = 2 and the atoms of cl on both sides = 2

left hand side = right hand side

so it is a balanced equation

Answer 2

Explanation:

example :- Ca(OH)2 + HCl = CaCl2 + H2O

so now I am balancing it

ca =2 times

OH (hydroxide ) =2 times

cl = 2 times

h= 2 times

now see ,

Ca(OH)2 it will remain same because there is already 2 times calcium

2HCl = cl and h becomes 2 now

then,

CaCl2 it will remain same too

2H2O I have also made h 2 here

Ca(OH) 2 + 2 HCl = CaCl2 +H2O

now it is balanced
