Identifying and Balancing Chemical equations

Front

What is a chemical equation?

Back

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

Front

What does it mean to balance a chemical equation?

Back

Balancing a chemical equation means ensuring that the number of atoms of each element is the same on both sides of the equation.

Front

What are reactants in a chemical reaction?

Back

Reactants are the starting substances that undergo a chemical change in a reaction.

Front

What are products in a chemical reaction?

Back

Products are the substances formed as a result of a chemical reaction.

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

How do you identify a synthesis reaction?

Back

A synthesis reaction occurs when two or more reactants combine to form a single product.

Front

How do you identify a decomposition reaction?

Back

A decomposition reaction occurs when a single compound breaks down into two or more simpler products.

Front

What is a single replacement reaction?

Back

A single replacement reaction occurs when one element replaces another element in a compound.

Front

What is a double replacement reaction?

Back

A double replacement reaction occurs when the ions of two compounds exchange places in an aqueous solution to form two new compounds.

Front

How do you determine the number of atoms in a compound?

Back

To determine the number of atoms in a compound, multiply the subscript of each element by the coefficient in front of the compound.
