I have this question:
What is the pH of a solution made by dissolving 6.75 g of NH4Cl and 2.80 g of NH3 in 200ml of water the Ka for ammonium is 5.6 x 10^-10.
The answer i came up with is 3.20. Did I get the right answer or did i do something wrong
I also have another problem:
The following reaction occurs at 1000 degree celcius with a Kc of 255. What are the equilibrium concentrations of all reactants and products if originally you have 0.250M [CO] and 0.175M [Cl2]?
when i try to solve the quadratic for this problem i keep getting two positive numbers. am i doing something wrong here or am i suppose to use one of those numbers? ( i get 0.26 and 0.17 )
