Front

What is a balanced chemical equation?

Back

A balanced chemical equation has the same number of each type of atom on both sides of the equation, indicating that mass is conserved during the reaction.

What is the volume of one mole of gas at STP?

Back

At standard temperature and pressure (STP), one mole of an ideal gas occupies 22.4 liters.

Front

What is the significance of the point where solid, liquid, and gas phases coexist?

Back

This point is known as the triple point, where all three phases of a substance are in equilibrium.

Front

What type of reaction is represented by the equation S₈ (s) + 8O₂ (g) --> 8SO₂ (g)?

Back

This is a combustion reaction, where a substance reacts with oxygen to produce energy and new products.

Front

What is the law of conservation of mass?

Back

The law of conservation of mass states that mass cannot be created or destroyed in a chemical reaction; it can only change forms.

Front

What is a mole in chemistry?

Back

A mole is a unit of measurement in chemistry that represents 6.022 x 10²³ particles (atoms, molecules, ions, etc.).

Front

What is the difference between a physical change and a chemical change?

Back

A physical change alters the form of a substance without changing its chemical composition, while a chemical change results in the formation of new substances.

Front

What is a synthesis reaction?

Back

A synthesis reaction is a type of chemical reaction where two or more reactants combine to form a single product.

Front

What is the formula for calculating the number of moles?

Back

The number of moles can be calculated using the formula: moles = mass (g) / molar mass (g/mol).
