Identify each of the following statements as being most similar to a hypothesis, a law, or a theory. Explain your reasoning. a) Falling barometric pressure precedes the onset of bad weather.

b) All life on earth has evolved from a common, primitive organism through the process of natural selection.

c) My truck’s gas mileage has dropped significantly, probably because it’s due for a tune-up.

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).

explanation:

the answer to your question is c
