Which gas helps cakes and bread rise?

Answer and explanation

Correct answer: Carbon dioxide

Sodium hydrogen carbonate in baking powder produces carbon dioxide on heating or when it reacts with an acid. Bubbles of this gas expand the batter or dough, making cakes and bread rise. Oxygen supports combustion, but it does not cause the rising. Exam tip: Remember that baking powder and baking soda release carbon dioxide.
