Question

When the equation KCIO3(s)>KCI(s)+O2(g) is balanced, the coefficient of KCIO3 is what?

Answer 1

The coefficient of
`2 KClO_(3)` is 2

Step-by-step explanation:

The Balanced Chemical equation is :

`2 KClO_(3)\rightarrow 2 KCl + 3O_(2)`

This reaction is balanced because total number of atoms of different elements in reactant is equal to total number of atoms in products.

Reactant : 2
`KClO_(3)`

Number of K atoms = (2)1 = 2

Number of Cl atoms = (2)1 = 2

Number of O atoms = (2)3 = 6

Product : 2 KCl and 3
`O_(2)`

In KCl

Number of K atoms = (2)1 = 2

Number of Cl atoms = (2)1 = 2

In
`3O_(2)`

Number of O atoms = (3)2 = 6

So ,

this equation is balanced and follow Law of Conservation of Mass because :

Number of K atom in reactant = product = 2

Number of Cl atom in reactant = product = 2

Number of O atom in reactant = product = 6
