Categorizing and Balancing Chemical Reactions

Front

What are reactants in a chemical equation?

Back

Reactants are the substances that undergo a chemical change in a reaction, found on the left side of a chemical equation.

Front

What are products in a chemical equation?

Back

Products are the substances that are formed as a result of a chemical reaction, found on the right side of a chemical equation.

Front

What does the arrow in a chemical equation represent?

Back

The arrow represents the direction of the reaction, indicating that reactants yield products.

Front

What are coefficients in a chemical equation?

Back

Coefficients are the numbers placed before compounds in a chemical equation to indicate the number of molecules or moles of that substance.

Front

What are subscripts in a chemical formula?

Back

Subscripts are the small numbers written after an element in a chemical formula that indicate the number of atoms of that element in a molecule.

Front

How do you balance a chemical equation?

Back

To balance a chemical equation, adjust the coefficients of the reactants and products to ensure that the number of atoms of each element is the same on both sides.

Front

What is the law of conservation of mass?

Back

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.

Front

What is a skeleton equation?

Back

A skeleton equation is a chemical equation that shows the reactants and products but not the coefficients needed to balance it.

Front

What is the difference between a balanced and unbalanced equation?

Back

A balanced equation has equal numbers of each type of atom on both sides, while an unbalanced equation does not.

Front

What is a double displacement reaction?

Back

A double displacement reaction is a type of chemical reaction where two compounds exchange ions to form two new compounds.
