If KCI is quickly cooled from 40°C to 10°Chow many grams of crystals (will precipitate out) will be formed?

i believe you are right for all except the 3rd ( look at sqdancefan his answer is much better)

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.
