A sample of 8.69 g of Zn(OH)2 is added to 155.0 mL of 0.750 M H2So4. (a) Write the chemical equation for the reac- tion that occurs. (b) Which is the limiting reactant in the re- action? (c) How many moles of Zn(OH)2, H2SO4, and ZnSO4 are present after the reaction is complete?

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.
