Give the mole ratio used for this question: {{ What is the mole of Cr(NO3)3 when 0.85 mol of Pb(NO3)4 reacts with Chromium using the following equation: ___Cr + ___Pb(NO3)4 ---> ___ Cr(NO3)3 + Pb }}

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.
