Question

The coefficients for the equation are:

KClO3 =
KCl +
O2

Answer 1

Answer:

$2KClO_{3} -----> 2KCl + 3O_{2}$

The Coefficient of the equation is in the ratio 2:2:3

Explanation:

Given KClO3 -----> KCl + O2

Looking at the above equation, we can tell that it's not balanced.

To balance it, we would ensure there are equal numbers of reactants and product.

$2KClO_{3} -----> 2KCl + 3O_{2}$

Let the Coefficient of Reactants be denoted by Cr

Coefficient of Product be denoted by Cp

The Reactant is KClO3

The products are KCl and O2

Hence, Cr(KClO3)=2. Cp(KCl)=2. Cp(O2)=3.

Therefore, the coefficients are 2,2,3 respectively.

Answer 2

Answer:

The coefficient of $KClO_{3}$  , KCl and $O_{2}$ are 2, 2 and 3 respectively.

Explanation:

The heating of $KClO_{3}$ to give KCl and oxygen gas is an example of decomposition reaction.

The balanced reaction for the decomposition of $KClO_{3}$ is shown below

$2KClO_{3}\rightarrow 2KCl+3O_{2}$

The coefficient of $KClO_{3}$ is 2

The coefficient of KCl is 2

The coefficient of $O_{2}$ is 3
