Chemical Equations Flashcard

The Law of Conservation of Mass states that mass is neither created nor destroyed in a chemical reaction; the total mass of reactants equals the total mass of products.

The reactants are $$H_2 + O_2$$ .

A balanced chemical equation has equal numbers of each type of atom on both sides of the equation, reflecting the Law of Conservation of Mass.

The equation is already balanced as it has one calcium, one carbon, and three oxygens on both sides.

The total number of atoms on each side is 10.

A reactant is a substance that undergoes change during a chemical reaction.

A product is a substance that is formed as a result of a chemical reaction.

Balancing chemical equations ensures that the Law of Conservation of Mass is upheld, showing that matter is conserved during the reaction.

A chemical equation is a symbolic representation of a chemical reaction, showing the reactants and products.

Considering polyatomic ions as units means treating them as single entities rather than balancing each atom individually.
