What is molarity?

Back

Molarity is a measure of the concentration of a solute in a solution, expressed as moles of solute per liter of solution (mol/L).

Front

How do you calculate molarity?

Back

Molarity (M) = moles of solute / liters of solution.

Front

What is a saturated solution?

Back

A saturated solution is a solution that contains the maximum amount of solute that can be dissolved at a given temperature.

What is the solubility of KCl in water at 70°C?

Back

At 70°C, the solubility of KCl is approximately 46g per 100g of water.

Front

What is vaporization?

Back

Vaporization is the process by which a liquid turns into a gas, which can occur through evaporation or boiling.

Front

What is the difference between evaporation and boiling?

Back

Evaporation occurs at the surface of a liquid at any temperature, while boiling occurs throughout the liquid at a specific temperature (boiling point).

Front

What does it mean for a chemical equation to be balanced?

Back

A balanced chemical equation has the same number of each type of atom on both sides of the equation, following the law of conservation of mass.

Front

What is a decomposition reaction?

Back

A decomposition reaction is a type of chemical reaction where one compound breaks down into two or more simpler substances.

Front

What are the products of the decomposition of silver chloride (AgCl)?

Back

The products of the decomposition of AgCl are silver (Ag) and chlorine gas (Cl2).

Front

What is the formula for calculating moles from grams?

Back

Moles = mass (g) / molar mass (g/mol).
