Balancing Chemical Equations

Front

What is a balanced chemical equation?

Back

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

Front

What is the law of conservation of mass?

Back

The law of conservation of mass states that mass cannot be created or destroyed in a chemical reaction; it can only change forms.

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 for each element is equal on both sides.

Front

What is a 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.

Front

What is a reactant?

Back

A reactant is a substance that undergoes a chemical change in a reaction, found on the left side of a chemical equation.

Front

What is a product?

Back

A product is a substance that is formed as a result of a chemical reaction, found on the right side of a chemical equation.

Front

What does it mean if a reaction is classified as 'synthesis'?

Back

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

Front

What does it mean if a reaction is classified as 'decomposition'?

Back

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

Front

What does it mean if a reaction is classified as 'single replacement'?

Back

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

Front

What does it mean if a reaction is classified as 'double replacement'?

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.
