# How do you write the formula for this reaction: Potassium chlorate decomposes to potassium chloride and oxygen gas?

Nov 3, 2016

Reaction is $2 K C l {O}_{3}$ $\rightarrow$ $2 K C l$ $+$ $3 {O}_{2} \uparrow .$

#### Explanation:

Formula for Potassium chlorate is $K C l {O}_{3}$.
Formula for Potassium chloride is $K C l .$
Formula for Oxygen gas as molecule is ${O}_{2.}$

$\therefore$ Reaction is : $K C l {O}_{3}$ $\rightarrow$ $K C l$ $+$ ${O}_{2} \uparrow .$

Now, balancing the equation, it comes to be :
$2 K C l {O}_{3}$ $\rightarrow$ $2 K C l$ $+$ $3 {O}_{2} \uparrow .$
