Please help me !! 1) How do molecules move to the location of the chemical change?
2) How do molecules move away from
the location of the chemical change?

Look below plz :))

Explanation:

1.) In a chemical change, the molecules in the reactants interact to form new substances. In a physical change, like a state change or dissolving, no new substance is formed. Explain that another way to say that no atoms are created or destroyed in a chemical reaction is to say, “Mass is conserved.”

2.) Carbon Dioxide and Water Out: During combustion, the atoms in ethanol and oxygen are rearranged into carbon dioxide and water. The carbon dioxide and water leave the top of the flame.

because the light is a great source of energy for the plants to survive. (i hope this )
