Question

38 which gas causes quick breads to rise? a carbon b carbon oxide c carbon dioxide d carbon monoxide

Explanation:

In quick breads, leavening agents (like baking powder or baking soda) react to produce carbon dioxide gas. This gas forms bubbles, causing the dough/batter to rise. Carbon is an element, carbon oxide is a general term (not specific), and carbon monoxide is toxic and not involved in leavening. So the correct gas is carbon dioxide.

Answer:

C. Carbon Dioxide
