What is a chemical reaction?
—A chemical reaction involves combining elements to form new substances.
Why is balancing equations important?
—Balancing equations ensures that the number of atoms is conserved during a reaction.
What are reactants and products in a chemical reaction?
—Reactants are the substances you start with, and products are the substances you end up with.
What are stoichiometric coefficients?
—Stoichiometric coefficients indicate the ratio of atoms or molecules in a chemical reaction.
What states of matter can be involved in a reaction?
—Chemical reactions can involve solids, liquids, gases, or aqueous solutions.
