Question

which statement best describes evidence that a chemical reaction occurs as a cake bakes?
the water in the cake batter evaporates
the cake rises as gas bubbles form in the baking cake
the cake takes the shape of the container in which it started
the water in the cake batter is used to keep the cake moist as it bakes

Explanation:

A chemical reaction produces a new substance. When gas bubbles form in the baking cake causing it to rise, it indicates a chemical change due to the production of gas from chemical reactions between ingredients like baking powder and acids in the batter. Evaporation of water is a physical change. Taking the shape of a container is a physical property. Using water to keep moist is a physical - moisture related process.

Answer:

The cake rises as gas bubbles form in the baking cake
