Question- Calculate the pH at the equivalence point for the titration of 0.200 M methylamine (CH3NH2) with 0.200 M HCl. The Kb of methylamine is 5.0× 10-4. pH=?
How do I fix this depict me complete computation so I can understand
How many grams of dry NH_4Cl need to be added to 2.10 L of a 0.100 it M solution of ammonia, NH_3, to prepare a buffer solution that has a pH of 8.84? K_b for ammonia is 1.8 * 10^{-5}
excess permanganate remains after the reaction period, a small amount of ethanol
Water in an enclosed vessel at 17°C contains a concentration of dissolved oxygen of 6 mg/L. At equilibrium, determine the concentration of oxygen in the space above the water in molal fraction. and the total pressure in the vessel. Henry's law con..
Show that the proton condition for a NH4Cl solution is a linear combination of the mass balance equations and the charge balance equation.
When a sample of H2S(g) (9.811 mol) is placed in 180.0 L reaction vessel at 724.0 K and allowed to come to equilibrium the mixture contains 0.01627 mol/L of S2(g). What is the equilibrium concentration (mol/L) of H2S(g)? 2H2S(g) = S2(g)+2H2(g)
Presume that data were collected for 10000 sets of automobile brakes. The mileage at which each set had been 80% worn through was recorded. The average was 62700 as well as the standard deviation was 10400 miles.
A 12 m 11 m 3.0 m basement had a high radon content. On the day the basement was sealed off from its surroundings so that no exchange of air could take place.
