How would the absence of sunlight affect a plant's ability to grow?
to provide fuel for cell processes
A precipitate formed.
chemical change
condensation
Gas was produced and lost to the environment.
Burning is a chemical change. The paper reacts with the oxygen in the air, producing heat and light.
