KClO3→ KCl+. O2

Answer 1

got it correct on edge

Step-by-step explanation:

Answer 2

2KClO₃ → 2KCl + 3O₂

Step-by-step explanation:

The unbalanced expression is given as:

KClO₃ → KCl + O₂

The reaction equation above is unbalanced and we need to choose between the numbers 2,3,4 and 5 to finally the correct expression that will obey the law of conservation of mass.

aKClO₃ → bKCl + cO₂

Let a, b and c be the numbers that will balance the expression;

Conserving K;

a = b

Conserving Cl;

a = b

Conserving O;

3a = 2c

let a = 1, b = 1 and c =
`(3)/(2)` multiply through by 2;

a = 2, b = 2 and c = 3

So, the balance expression insert;

2KClO₃ → 2KCl + 3O₂
