15 pts ! which chemical equation below does not illustrate the law of conservation of mass? al4c3 + 3h2o yields ch4 + 4al(oh)3 2 nacl + cao yields na2o + cacl2 3 lioh + fe(no3)3 yields 3lino3 + fe(oh)3 zn + 2hcl yields zncl2 + h2

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.
