In a study of the conversion of methane to other fuels, a chemical engineer mixes gaseous methane and gaseous water in a 0.501 l flask at 1043 k. at equilibrium, the flask contains 0.169 mol of co gas, 0.257 mol of h2 gas, and 0.255 mol of methane. what is the water concentration at equilibrium (kc = 0.30 for this process at 1043 k)? enter to 4 decimal places. hint: look at sample problem 17.7 in the 8th ed silberberg book. write a balanced chemical equation. write the k expression. calculate the equilibrium concentrations of all the species given (moles/liter). put values into k expression, solve for the unknown.

Which form of relativism states that people rely on their own standards of right and wrong when making a decision?

How does a large body of water, such as the ocean, influence climate?

Answer asap need by wednesday morning explain how a buffer works, using an ethanoic acid/sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
