Fill in the coefficients that will balance the following reaction: Cr2(SO4)3 + AgNO3
Cr(NO3)3 +
Ag2SO4

3Cr(NO3)3 + 4Ba(OH)2 → 3Ba(NO3)2 + 4H2O + Ba(CrO2)2

7Ba(OH)2 + 2Cr(NO3)3 → Ba(CrO2)2 + 2NaOH

FeCl2 + Ag2SO4→ 2AgCl + FeSO4

3Ag2SO4 + 2FeCl3 → 6AgCl + Fe2(SO4)3

Cu + Ag2SO4 → 2Ag + CuSO4

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.

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
