1. List the species present at equilibrium in a solution with the following composition:

NH4Cl = 0.0200 mol/L NaOH = 0.0430 mol/L

H2SO4 = 0.0150 mol/L NaNO3 = 0.0100 mol/L

2. Write the n equations for n unknowns describing the equilibrium composition of

this system.

3. Make a spreadsheet and use Excel’s Solver function to determine the equilibrium

pH and concentrations of all species in this solution.

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.
