Drag and Drop if the statement is True or False Catalysts are not used up by the reaction. blank Catalysts provide an alternate reaction pathway with a lower activation energy. blank Catalysts increase the rate of the forward reaction. blank Catalysts decrease the rate of the reverse reaction. blank Catalysts shift the equilibrium position of the reaction to the right. g

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

the formula mass of a molecule or a compound is the sum of the atomic weights of the atoms in its empirical formula

(that's what i know about formula mass)
