What is the pH of a solution that is prepared by dissolving 6.69 grams of lactic acid (formula weight = 90.08 grams/mol) and 8.77 grams of sodium lactate (formula weight = 112.06 grams/mole) in water and diluting to 700.00 mL? The Ka for lactic acid is 0.000137.

18. use the activity series to predict whether the following synthesis reaction will occur. write the chemical equations for the reaction if it's predicted to occur. (s) + o2(g) -> *note: it is possible.*

Select all that apply. a beta particle: is electromagnetic energy is an electron has zero charge is emitted from the nucleus has a +2 charge has a -1 charge
