An ion with 5 protons, 6 neutrons, and a charge of 3 has an atomic number of

You wish to prepare a buffer consisting of acetic acid and sodium acetate with a total acetic acetate plus acetate concentration of 250 mm and a ph of 5. what concentrations of acetic acid and sodium acetate should you use

Calculate the ph of a .10m nh4cl solution. the kb value for nh3 is 1.8×10^-5

Areaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:
