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 matter is conserved during the reaction.

Front

What does the Law of Conservation of Matter state?

Back

The Law of Conservation of Matter states that atoms are not created or destroyed during a chemical reaction.

Front

How do you determine if a chemical equation is balanced?

Back

Count the number of atoms of each element on both sides of the equation. If they are equal, the equation is balanced.

Front

What is the first step in balancing a chemical equation?

Back

Identify the number of atoms of each element in the reactants and products.

Front

What is the balanced form of the equation: HgO --> Hg + O2?

Back

2HgO --> 2Hg + O2.

Front

How many atoms of carbon are in C6H12O6?

Back

There are 6 atoms of carbon in C6H12O6.

Front

What is the purpose of balancing chemical equations?

Back

Balancing chemical equations ensures that the same amount of matter is present before and after a chemical reaction.

Front

What does it mean if an equation is unbalanced?

Back

An unbalanced equation indicates that the number of atoms of one or more elements is different on each side, violating the Law of Conservation of Matter.

Front

What is a reactant in a chemical reaction?

Back

A reactant is a substance that undergoes change during a chemical reaction.

Front

What is a product in a chemical reaction?

Back

A product is a substance that is formed as a result of a chemical reaction.
