Calculate the pH in a solution prepared by dissolving 0.10 mol of solid NH4Cl in .500 L of 0.40 M NH3. Assume that there is no volume change.
If the combustion gases consist of CO2, H2O, CO, O2, and N2 that exit at 1200 K and 2 atm, determine (a) the equilibrium composition of the product gases and (b) the rate of heat transfer from the combustion chamber. Is it realistic to disregard t..
When solid CaCO3 is heated, it decomposes to give solid CaO and CO2 gas. A volume of 285mL of gas is collected over water at a total pressure of 730mmHg and 16 °C. The vapor pressure of water at 16 °C is 14 mmHg. CaCO3(s)→CaO(s)+CO2(g)
