Amplify Chemical Reactions Ch. 1-2

Front

What are reactants in a chemical reaction?

Back

Reactants are the substances that undergo a chemical change in a reaction. They are found on the left side of the chemical equation.

Front

What are products in a chemical reaction?

Back

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

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 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

What is a molecule?

Back

A molecule is a group of two or more atoms bonded together, representing the smallest fundamental unit of a chemical compound.

Front

How many atoms are in one molecule of water (H2O)?

Back

There are 3 atoms in one molecule of water: 2 hydrogen atoms and 1 oxygen atom.

Front

What is a property in chemistry?

Back

A property is a characteristic or trait of a substance, such as color, melting point, or boiling point.

Front

What is the difference between physical and chemical properties?

Back

Physical properties can be observed without changing the substance's identity, while chemical properties describe how a substance reacts to form new substances.

Front

What is the melting point?

Back

The melting point is the temperature at which a solid becomes a liquid.

Front

What is the boiling point?

Back

The boiling point is the temperature at which a liquid becomes a gas.
