A solution is made by mixing 8.00 (millimoles) of and 1.00 of the strong base. What is the resulting pH?More strong base is added until the equivalence point is reached. What is the pH of this solution at the equivalence point if the total volume is 42.0 ?
what is the expected boiling point of a brine solution containing 30.00g of KBr dissolved in 100.0g of water?
if 400 ml of a 0.100M acetic acid and 200 ml of 0.100m solution acetate are mixed, what is the pH?
Chemical analysis of the two compounds reveals that 0.25 mol ACl 2 has a mass of 100.0 g and 0.50 mol BCl 2 has a mass of 125.0 g. Determine what are the molar masses of ACl 2 and BCl 2 ?
When NH3 is prepared from 28 g N2 and excess H2 the theoretical yield of NH3 is 34 g. When this reaction is carried out in a given experiment, only 30. g is produced.
A sample of ammonia gas was allowed to come to equilibrium at 400 K.2NH3(g) ↔ N2(g) + 3H2(g) At equilibrium, it was found that the concentration of H2 was 0.0584 M, the concentration of N2 was 0.0195 M, and the concentration of NH3 was 0.430 M.
Find out the concentration of this solution 1) in m (molality), 2) XHX (mole fraction of HX), 3)% w/w (percent by mass) if solvent in this solution is H 2 O. ?
Calculate the equilibrium concentrations of NH3 and H2S if a sample of solid NH4HS is placed in a closed vessel and decomposes until equilibrium is reached
