How to calculate the pH of 0.375 L of a 0.18 M acetic acid-0.29 M sodium acetate buffer before and after the addition of (a) 0.0060 mol of KOH and (b) 0.0060 mol of HBr. (assumption is that the volume remains consant)
A mixture of gases contains 7.5g hydrogen and 29.6 nitrogen with a total pressure of 127 torr. Calculate the solubility of nitrogen gas
For a hypothetical gas-phase reaction that is second order in A and third order in B, by what factor does the rate change if pA is decreased by 4 times and pB is doubled
At a certain temperature, the Kp for the decomposition of H2S is 0.726 H2S = H2+S initally only H2S is present at a pressure of 0.126 atm in a closed container. what is the total pressure in the container at equilibrium?
Describe the error that has occured; that is , is the mass of the anhydrous salt remaining in the crucible reported as being too high or low? Explain.
A home swimming pool contains 145 m3 of water. At the beginning of the swimming season, the water must be heated from 18 to 31°C. How many joules of heat energy must be supplied?
Calculate the concentration of magnesium and calcium in ppm. Record your answers as ppm Mg2+, and Ca2+ espectively. For each answer indicate the ppm as CaCO3 also.
