You are performing an experiment in the lab and have reactant A and Reactant B The total mass of both reactant before the experiment 15.0 grams you placed the reactant an open beaker to react without a name the beaker is cold to the touch after word you measure the product in the container and only get a mass of 12.4 grams what happened to the rest of the mass One of the products was possibly a gas ?

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.
