Sodium oxide and carbon dioxide
Explanation:
When sodium carbonate decomposes sodium oxide and carbon dioxide is produced:
Na₂CO₃ → Na₂O + CO₂
- This kind of reaction is known as decomposition reaction.
- In a decomposition reaction,
- In this kind of reaction, two or more products form from a single reactant.
- The breakdown of a compound into its component individual elements or other compounds falls into this reaction category.

Answer: Because it is a giant fire ball
In chemical reactions, the actual yield is not the same as the expected yield . Actual yield is lower than the theoretical yield . Then we have to find the yield percentage. To see what percentage of the theoretical yield is the actual yield.
Percent yield = actual yield / theoretical yield x 100%
Percent yield = 24.6/55.9 x100%
Percent yield = 44%
It has to be understood that 2 moles of oxygen are there in each mole of PbO2. Then it has to be calculated for 2 moles of oxygen.
Amount of oxygen = 2 * 5.43 moles
= 10.86 moles
Now it is also a fact that each mole of H2O contains 1 mole of oxygen. Then it can be easily concluded that 10.86 moles of water will be produced. I hope the procedure is clear enough for you to understand.
