Front

What is a chemical equation?

Back

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

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 the equation.

Front

What are products in a chemical equation?

Back

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

Front

What does the Law of Conservation of Mass state?

Back

The Law of Conservation of Mass states that matter cannot be gained or lost in a chemical reaction; it is conserved.

Front

What is a synthesis reaction?

Back

A synthesis reaction is a type of chemical reaction where two or more simple substances combine to form a more complex product.

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 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 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.

Front

How do you balance a chemical equation?

Back

To balance a chemical equation, adjust the coefficients of the reactants and products to ensure the same number of each type of atom on both sides.

Front

What is the coefficient in a chemical equation?

Back

A coefficient is a number placed in front of a chemical formula in an equation to indicate how many molecules or moles of that substance are involved.
