Question

Nick is researching why baking powder is a common baking ingredient. He learns that baking powder contains tartaric acid and sodium hydrogen carbonate. He also learns that when water is added to cake ingredients, a reaction occurs. It causes bubbles to form that make the cake rise. What gas is in the bubbles, and why do they form?

Answer 1

carbon dioxide gas

Step-by-step explanation:

Leavening may be achieved by the process of fermentation, which releases carbon dioxide gas. Bakers' yeast, composed of living cells of the yeast strain Saccharomyces cerevisiae, is available as a pressed cake and in a powdered form.
