The bubbles that make a baked cake light and tender come from the decomposition and carbonate acid H2 CO3 in the cake batter which are the likely products of this reaction?

The bubbles that make a baked cake light and tender primarily come from the production of carbon dioxide gas (CO2) during the chemical reactions involving baking powder or baking soda. When these leavening agents react with acidic components in the batter, they release carbon dioxide, which forms bubbles. These bubbles expand during baking, causing the cake to rise and creating a light, tender texture. Additionally, water vapor contributes to the overall leavening process as the cake bakes.
