For the reaction: CO(g) + H2O -> CO2(g) + H2(g) kp = 4.10 at 500 C. What are the concentrations of the gases at equilibrium, if the initial concentration of carbon monoxide and water vapor are both equal to 0.325 M? Can you explain me what is the formula and how did you do it?
Use the Henderson-Hasselbalch equation to calculate the pH of a buffer that is 0.158 M HClO and 0.099 M NaClO. The Kb for HClO is 3.45 x 10^-7.

Imagine that you have a 7.00 litre gas tank and a 3.00 litre gas tank. You need to fill one tank with oxygen and the other with acetylene to use in conjunction with your welding torch.
What is the value of the equilibrium constant for the reaction between Al(s) and Cd2+(aq), at 25 °C?
A rectangular block of plastic, measuring 1.34 cm by 2.27 cm by 1.39 cm, floats in the middle of the Pacific Ocean. The volume of sea water displaced by the plastic block is 3.35 cm3. Assuming the density of the sea water is 1.025 g/mL, what is th..
The calorimeter cup had several millimeters of water in it when you added the HCl in Step 16: b.) The base solution was added to the acid solution but was not stirred while temperature measurement were not made: c.) Some of the base splashed out o..
A carbon-hydrogen-oxygen containing compound yields 1.029 g CO2 and 0.198 g H2O in a combustion analysis( note that this means O2 was added the overall reaction) what is the empirical formula? if the Molar mass is 138.16 what is the molecular form..
the volumetric flask during weighing by difference after recording the mass, how would it affect the final result for his calculated molecular mass of the metal carbonate?
Trehalose is the major sugar in the hemolymph (blood) of many insects. Insects have open circulatory systems that bathe the tissues of the animal.
