What term expresses the ratio of moles of reactants and products according to the coefficients in the balanced chemical equation? a) mole ratio b) reactant ratio c) product ratio d) yield ratio e) none of the above

A) mole ratio

Explanation:            

A mole ratio, also known as a mole-to-mole ratio, is the ratio between the amounts in moles of one reactant/product to the moles of the other reactant/product. This ratio is determined considering the coefficients in a balanced chemical equation. This ratio is used in chemical problems as a conversion factor between the compounds involved in the reaction.

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.
