3) In the combustion reaction of methane gas: CH4 (8) + O2(g) CO2 (g) + 2 H2O (8)
4.0 X 10 exp 23 molecules of CH4 was used. Determine
(a) the moles of CO2 produced
(b) using your answer in (a), calculate the volume of CO2 produced at
STP
(c) the volume of oxygen used in the reaction at STP

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.
