Law of Conservation of Matter

Front

What is the Law of Conservation of Matter?

Back

The Law of Conservation of Matter states that matter cannot be created or destroyed in a chemical reaction; it can only change forms.

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 a chemical equation.

Front

What are products in a chemical equation?

Back

Products are the substances that are formed as a result of a chemical reaction, found on the right side of a chemical equation.

Front

What does a coefficient in a chemical equation represent?

Back

A coefficient indicates the number of molecules or moles of a substance involved in a reaction.

Front

What does a subscript in a chemical formula indicate?

Back

A subscript indicates the number of atoms of an element in a molecule.

Front

How do you determine the total number of atoms in a molecule?

Back

To find the total number of atoms in a molecule, add the number of atoms of each element, considering their subscripts.

Front

What is the significance of balancing a chemical equation?

Back

Balancing a chemical equation ensures that the number of atoms for each element is the same on both sides, adhering to the Law of Conservation of Matter.

Front

What is the role of oxygen (O2) in combustion reactions?

Back

In combustion reactions, oxygen (O2) acts as a reactant that combines with a fuel to produce energy, carbon dioxide, and water.

Front

What is the difference between a chemical equation and a chemical reaction?

Back

A chemical equation is a symbolic representation of a chemical reaction, showing the reactants and products, while a chemical reaction is the actual process that occurs.

Front

What does it mean if a chemical equation is not balanced?

Back

If a chemical equation is not balanced, it means that the Law of Conservation of Matter is violated, as the number of atoms of each element is not equal on both sides.
