A variety of ions with Na+, K+, NH4+,Pb2+, Fe2+, NO3-, Cl-, Br-, S2-, and CO32- are added in a beaker of H2O, which substances would you expect to find, If you analyzed the precipitates?
considering the given reaction: CO (g) + H2O (g) <=> CO2 (g) + H2 (g), an equilibrium mixture contains 0.500 moles each of CO2 and H2 gas, and 0.200 moles each of CO and water vapor in a 1.00 Litre container. Determine how many moles of CO2 would have to be combined at constant temperature and volume to increase the amount of CO to 0.300 moles?
