Describe the preparation of: A/ 5.00L of 0.05 KMnOu from the solid reagent.

B/ 200 mL of 1% (W/v) aqueous Cuso4 from 0.365 M CuSo4 Solution.

C/ 1.50 L of o.215 M NaOH from the concentrated commercial reagent (5% NaOH (w/w) Sp. gr = 1-526)

D/ 1.5L of a solution that is 12.0 ppm in K+

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.
