At room temperature the equilibrium constant Kc for the reaction: 2NO(g)=N2(g)+O2(g) is 1.4x10^30. In the atmosphere at room temp. the concentration of nitrogen gas is 0.33 mol/L and the concentration of oxygen gas is about 25% that value. Calculate the e...

The equlibrium constant Kc for the reaction: has the value of 4.00 at 500K. If a mixture of 1.00 mol CO and 1.00 mol H2O is allowed to reach equilibrium at this temperature in a 1.00L flask, calculate the equilibrium concentrations of each species in the...

What is the pH of a solution that is 0.20 M CH3COOH and 0.10 M CH3COONa?

I need to know if I am anywhere in solving this problem: Please tell me if this is correct. The pH of a solution: 0.20 M CH3COOH and 0.10 M CH3COONa pH=pKa+log{[CH3COONa]/[CH3COOH]} pH= -log(1.8x10-5)+log{0.10/0.20} pH= 4.74+log 0.50= 4.74-0.30= 4.44

the banks contains quarters , dime and nickels. The number of dimes is 1 less than the number of nickels. The number of nickels is 2 more than twice the number of quarters. The coins are worth $5.70. How many nickels are there?

Consider the titration of 100.0 mL of 0.110 M NaOH with 1.00 M HBr. Find the pH at the following volumes of acid added and make a graph of pH versus Va:Va = 0,2,5,8,10,10.1,11,11.1, and 12mL. Compute Ve, first.

Kc=(x)(x)/(1-x)(1-x) What is x in this equation and is is 4.0 Kc?

Please tell me if this is correct. The pH of a solution: 0.20 M CH3COOH and 0.10 M CH3COONa pH=pKa+log{[CH3COONa]/[CH3COOH]} pH= -log(1.8x10-5)+log{0.10/0.20} pH= 4.74+log 0.50= 4.74-0.30= 4.44
