If a 5kg object slows down from 13 m/s to 5 m/s in 2s, what is its change in momentum?

Reaction rate depends on how many molecules are coming into contact with each other with enough energy to react. increasing the temperature of the reactants will increase -

If you add 10ml of hot water to 10ml of cold water and the change in tempature 8°c calculate how much energy is gained by the cold water

How many grams of co(g) are there in 74.5 ml of the gas at 0.933 atm and 30o c?
