Answer
1Ca(ClO₃)₂ → 1CaCl₂ + 3O₂
Step-by-step explanation
Given chemical equation:
Ca(ClO₃)₂ → CaCl₂ + O₂
The Algebraic Method of balancing chemical equation is given by the formula below:
aA + bB → cC + dD
Where; a, b, c, and d are the coefficients of the reactants A and B, and products C and D respectively
Considering the given equation:
Put unknown coefficient in front of each species
bCa(ClO₃)₂ → cCaCl₂ + dO₂
For Ca; bCa = cCa ------(i)
For Cl; 2bCl = 2cCl ------(ii)
For O; 2 x 3 x bO = 6bO = 2dO ------(iii)
Let assign b = 1
Therefore, from (i); b = c ⇒ b = c = 1
From (ii); b = c = 1
From (iii); 6b = 2d
Substitute b = 1 into (iii)
6(1) = 2d
d = 6/2 = 3
The coefficients b = 1, c = 1, and d = 3
Hence, the balanced equation is
bCa(ClO₃)₂ → cCaCl₂ + dO₂
1Ca(ClO₃)₂ → 1CaCl₂ + 3O₂
