Questions

Question 1 Multiple Choice (Single Answer)

What is the law of constant proportions?

  1. The law that states that a chemical compound always contains the same elements in the same proportions by mass.
  2. The law that states that the rate of a chemical reaction is proportional to the concentration of the reactants.
  3. The law that states that the equilibrium constant for a chemical reaction is independent of the initial concentrations of the reactants.
  4. The law that states that the heat of a chemical reaction is equal to the difference in the heats of formation of the reactants and products.
