Balancing and Identifying Chemical Equations

Front

What is a balanced chemical equation?

Back

A balanced chemical equation has equal numbers of each type of atom on both sides of the equation, indicating that mass is conserved during the reaction.

Front

What is the purpose of balancing chemical equations?

Back

Balancing chemical equations ensures that the law of conservation of mass is followed, meaning that matter is neither created nor destroyed in a chemical reaction.

Front

What are coefficients in a chemical equation?

Back

Coefficients are whole numbers placed in front of chemical formulas in a balanced equation to indicate the number of molecules or moles of each substance involved in the reaction.

Front

What is a single replacement reaction?

Back

A single replacement reaction is a type of chemical reaction where one element replaces another element in a compound.

Front

What is a decomposition reaction?

Back

A decomposition reaction is a type of chemical reaction where a single compound breaks down into two or more simpler products.

Front

What is a synthesis reaction?

Back

A synthesis reaction is a type of chemical reaction where two or more reactants combine to form a single product.

Front

What is a double replacement reaction?

Back

A double replacement reaction is a type of chemical reaction where the anions and cations of two different compounds exchange places, forming two new compounds.

Front

What is the difference between a reactant and a product?

Back

Reactants are the starting substances in a chemical reaction, while products are the substances formed as a result of the reaction.

Front

How do you identify the limiting reactant in a chemical reaction?

Back

The limiting reactant is the reactant that is completely consumed first in a chemical reaction, limiting the amount of product that can be formed.

Front

What is the significance of subscripts in a chemical formula?

Back

Subscripts indicate the number of atoms of each element in a molecule; for example, in H2O, the '2' indicates there are two hydrogen atoms.
