Chemical Reactions Practice

Front

What is a chemical reaction?

Back

A process in which substances (reactants) are transformed into different substances (products) through the breaking and forming of chemical bonds.

Front

What are reactants in a chemical equation?

Back

The starting substances that undergo a chemical change in a reaction.

Front

What are products in a chemical equation?

Back

The substances that are formed as a result of a chemical reaction.

Front

How do you balance a chemical equation?

Back

By ensuring that the number of atoms of each element is the same on both sides of the equation, typically by adjusting coefficients.

Front

What is the law of conservation of mass?

Back

In a chemical reaction, mass is neither created nor destroyed; the total mass of reactants equals the total mass of products.

Front

What is a coefficient in a chemical equation?

Back

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

Front

What is the difference between an ionic and covalent bond?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons between atoms.

Front

What is solubility?

Back

The ability of a substance to dissolve in a solvent, typically water, to form a homogeneous solution.

Front

What are the solubility rules?

Back

Guidelines that predict whether a compound will dissolve in water based on its ionic components.

Front

What is a balanced chemical equation?

Back

An equation that has equal numbers of each type of atom on both sides, indicating that mass is conserved.
