P5 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 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 it mean for a chemical equation to be balanced?

Back

A balanced chemical equation has the same number of each type of atom on both sides, following the law of conservation of mass.

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 law of conservation of mass?

Back

The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction.

Front

How many atoms of hydrogen are in H2O?

Back

There are 2 atoms of hydrogen in one molecule of water (H2O).

Front

What is the coefficient in a chemical equation?

Back

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

Front

How many total atoms are in C6H12O6?

Back

There are 24 total atoms in one molecule of glucose (C6H12O6).

Front

What is the purpose of balancing chemical equations?

Back

Balancing chemical equations ensures that the same number of each type of atom is present on both sides, reflecting the conservation of mass.
