Double Puzzle
Answer the clues below by filling in the open boxes provided.
Then arrange the letters from the highlighted boxes to answer the
final riddle.
a. The sun supplies this.

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).

away from the curb

explanation:

the wheels would then hit the curb if it started to rolling, decreasing the chance of an accident.
