To balance the given equation 2NaHCO3 -> Na2CO3 + CO2, you need to determine the coefficients for each compound so that the number of atoms of each element is the same on both sides of the equation.
Here's the balanced equation:
2NaHCO3 -> Na2CO3 + CO2 + H2O
As you can see, the compound that needs to be added to balance the equation is H2O (water).
To balance the given chemical equation:
2NaHCO3 -> Na2CO3 + CO2
We need to ensure that the number of atoms is the same on both sides of the equation.
Let's analyze each option:
1. H2O: This option adds water molecules. However, there is already enough oxygen in the products since Na2CO3 already contains oxygen.
2. H2: This option adds hydrogen molecules. The hydrogen atoms are already balanced on both sides since NaHCO3 has two hydrogen atoms, and Na2CO3 has four hydrogen atoms.
3. CH2OH: This option adds methanol (CH2OH) to the products. However, it does not help in balancing any of the elements.
4. O2: This option adds oxygen molecules. Since there is one oxygen atom in NaHCO3 and three in Na2CO3, we need to add one more oxygen atom to balance the equation. Therefore, O2 is the correct choice.
So, the option that can be added to the products to balance the equation is O2.
