The concentration of H+ ion in gastric juice is 0.1 M. pH of the protons arise from blood =7.4.
compute the free energy change needed for transport of sufficient protons to make gastric juice of 1 litter at the temperature of 37 degree celsius hence expect above reaction will happen spontaneously?
the reaction of potassium in water is extremely exothermic, what would be the problem with adding a large piece of potassium to a small amount of water?
How much of methane gas will be produced in anaerobic decomposition assuming a complete conversion of MSW into CH4CO2NO, and SO2.
Three 10.00mL samples of juice were titrated with DCP that had a standardized concentration of 1.01x10-3M. The three titrations took an average of 13.82mL of DCP. Calculate the mass (in mg) in 50.00mL of juice. (MM Ascorbic Acid = 176.124 g/mol)
