Balance the equation

Observation

Question

Tap on the buttons to change the coefficients of the elements to balance the given chemical reaction.

Elements	Reactants	Products
Fe	2	3
C	2	3
O	2	3

Let us start with Fe, observe the number of atoms in the reactant and product side and look to make it equal on both sides.

\(\text{Fe}_2\text{O}_3~+\) \(\text{C} \rightarrow\) \(\text{Fe}~+\) \(\text{CO}_2\)

Identify the value of x:y, if the given chemical equation is balanced.
\(~~~~~~~~~~~~~~~~~~~~\text{xFe}~+~\text{yCl}_2 \rightarrow \text{2FeCl}_3\)

Oops!

You’ve missed something! Let’s go back to the observation tab and give it another shot!

1:2

2:1

2:3

3:2

Solution

Reactants	Elements	Products
2	Fe	2
6	Cl	6

The balanced chemical equation for the reaction of iron with chlorine is:
\(~~~~~~~~~~~~\text{2Fe}~+~\text{3Cl}_2 \rightarrow \text{2FeCl}_3\)
\(~~~~~~\) Thus, the value of x:y is 2:3.
