What is the effect of temperature on the solubility of a solute in a solvent?

Back

Increasing the temperature generally increases the solubility of a solute in a solvent.

Front

What are the reactants in a chemical equation?

Back

The substances that undergo a chemical change in a reaction, found on the left side of the equation.

Front

Define a catalyst.

Back

A substance that increases the rate of a chemical reaction without being consumed in the process.

Front

How do you determine the number of atoms in a compound?

Back

By using the coefficients and subscripts in the chemical formula.

Front

What is a saturated solution?

Back

A solution in which no more solute can dissolve at a given temperature.

Front

What is an unsaturated solution?

Back

A solution that can still dissolve more solute at a given temperature.

Front

What is a supersaturated solution?

Back

A solution that contains more dissolved solute than is required to reach equilibrium at a given temperature.

Front

What is the role of water in dissolving substances?

Back

Water acts as a solvent, breaking down solute particles and allowing them to disperse.

Front

What is the difference between reactants and products in a chemical reaction?

Back

Reactants are the starting materials, while products are the substances formed as a result of the reaction.

Front

What is the significance of the coefficients in a chemical equation?

Back
