To balance the chemical equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation.Given equation:
Let's analyze the options:1.
: This means 2 moles of
decompose to produce 1 mole of
and 2 moles of
. This is not balanced because there are 4 moles of
on the left side and only 1 mole of
on the right side.2.
: This means 2 moles of
decompose to produce 2 moles of
and 2 moles of
. This is balanced because there are 4 moles of
on both sides and 2 moles of
on both sides.3.
: This means 1 mole of
decomposes to produce 1 mole of
and 1 mole of
. This is not balanced because there are 2 moles of
on the left side and only 1 mole of
on the right side.4.
: This means 2 moles of
decompose to produce 4 moles of
and 1 mole of
. This is not balanced because there are 4 moles of
on the left side and only 4 moles of
on the right side.Therefore, the correct answer is
.
