Carbon dioxide is the result of the reaction between the yeast compounds and the gluten. The heat process causes the compounds to expel the carbon dioxide, which expands more than the oxygen in the bread.
Breads and quick breads expand because of air. In yeast breads the yeast eats the sugar and makes carbon dioxide that puts air into the bread. In quick breads a chemical reaction similar to vinegar and baking soda makes air that expands the bread. Bread that has been expended is softer to eat.
In a lime kiln calcium carbonate is heated to form quick lime and carbon dioxide. CaCO3 -> CaO + CO2
Quick bread is a type of bread that is leavened with baking powder or baking soda instead of yeast, making it faster to prepare and bake. Popular quick bread recipes include banana bread, zucchini bread, and pumpkin bread.
The most popular type of quick bread is banana bread.
Fizzing is done by the quick escape of carbon dioxide gas from carbonated water (called soda).
When marble is heated, it undergoes a chemical reaction called thermal decomposition. This reaction breaks down the calcium carbonate (CaCO3) in marble into calcium oxide (CaO) and carbon dioxide (CO2) gas.
bake Bread
Flour is the main ingredient in quick bread, forming the bulk of the product.
Quick bread is a type of bread that is leavened with baking powder or baking soda instead of yeast. It is called "quick" because it does not require the time-consuming process of proofing and rising that yeast bread does. This makes quick breads faster and easier to make.

The reaction of baking powder to release carbon dioxide bubbles is a chemical change because it involves the formation of new substances (carbon dioxide gas) due to a chemical reaction. The carbon dioxide bubbles cause the dough to rise through physical expansion, but the underlying process of gas production is a chemical change.
When carbon dioxide is passed through slaked lime (calcium hydroxide), calcium carbonate is formed. This reaction is called carbonation and it can be used to remove carbon dioxide from gas streams in industrial processes. The calcium carbonate forms as a solid precipitate, which can be easily removed from the system.
