How do you calculate Enthalpy of a reaction?

Back

ΔH = ΔH_products - ΔH_reactants

Front

What is Boyle's Law?

Back

The pressure and volume of a gas show an inverse relationship.

Front

What does pH measure?

Back

The amount of hydrogen (H+) ions.

Front

What is the formula for calculating the change in temperature?

Back

ΔT = q / mC

Front

What is the limiting reactant in a reaction?

Back

The reactant that is completely consumed first, limiting the amount of product formed.

Front

What is the relationship between temperature and volume in gases?

Back

According to Charles's Law, the volume of a gas is directly proportional to its temperature in Kelvin.

Front

What is the ideal gas law?

Back

PV = nRT, where P is pressure, V is volume, n is number of moles, R is the gas constant, and T is temperature.

Front

What is the significance of the gas constant (R) in the ideal gas law?

Back

R is a proportionality constant that relates the pressure, volume, and temperature of an ideal gas.

Front

What is the formula for calculating the number of moles?

Back

n = mass (g) / molar mass (g/mol)

Front

What is the relationship between pressure and volume in gases?

Back

According to Boyle's Law, the pressure of a gas is inversely proportional to its volume.
