Answer these three questions Mole to Mole: KClO3(s) KCl(s) + O2(g)
How many moles of KClO3 are needed to produce 50 moles of O2?

Mole to Mass: Calculate the mass of hydrochloric acid needed to react with 5.00 moles of zinc in a single replacement reaction.

Mass to Mass: Calculate the mass of sodium phosphate (Na3PO4) produced if 30.0g of sodium acetate (NaC2H3O2) and silver phosphate (Ag3PO4) react.

i dont know sorry

Explanation:

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.
