Balancing Equations and Types of Reactions

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 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 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 two compounds exchange ions or elements to form two new compounds.

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; it is conserved.

Front

How do you determine the coefficients in a balanced equation?

Back

Coefficients are determined by adjusting the numbers in front of the compounds to ensure that the number of atoms for each element is the same on both sides of the equation.

Front

What is the significance of the yields sign (→) in a chemical equation?

Back

The yields sign indicates the direction of the reaction, showing that reactants are transformed into products.
