Front

What type of reaction occurs between an acid and a base?

Back

Neutralization

Front

List the substances from most basic to acidic: lemon juice (pH 2), baking soda (pH 9), bleach (pH 12), milk (pH 6).

Back

bleach, baking soda, milk, lemon juice

Front

In Boyle's law, when pressure increases, what happens to the volume?

Back

decrease

Front

Define synthesis reaction in chemistry.

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 the pH scale used for?

Back

The pH scale measures the acidity or basicity of a solution, ranging from 0 (acidic) to 14 (basic), with 7 being neutral.

Front

What is the principle of conservation of mass in a chemical reaction?

Back

The principle 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 an acid-base neutralization reaction?

Back

An acid-base neutralization reaction occurs when an acid reacts with a base to produce water and a salt.

Front

What is Boyle's Law?

Back

Boyle's Law states that the pressure of a gas is inversely proportional to its volume at constant temperature.
