Unit 3 Flashcard Stoichiometry, Thermo Chem & Pressure, Molarity

Front

What is the change of state from a gas to a liquid?

Back

Condensation

Front

What happens to matter as its temperature increases?

Back

The particles gain kinetic energy.

Front

How do chemists describe the "strength" or concentration of a solution?

Back

Molarity.

Front

What is the formula to calculate heat absorbed or released?

Back

q = m × c × ΔT (where q = heat, m = mass, c = specific heat, ΔT = change in temperature)

Front

What is the specific heat of aluminum?

Back

0.900 J/g°C.

Front

How do you calculate the number of moles in a solution?

Back

Moles = Molarity × Volume (in liters).

Front

What is the molarity of a solution?

Back

Molarity is the number of moles of solute per liter of solution.
