The decomposition of ammonia is 2NH3(g) = N2(g) + 3H2(g). If Kp is 1.5x10^3 at 400 degrees C, what is the partial pressure of ammonia at equilibrium when N2 is 0.10 atm and H2 is 0.15 atm?
The compound butane consists of only C and H. If 0.531g of butane is burned in oxygen and produces 1.61g of CO2 and 0.823g of H2O, what is the empirical formula of butane
What combination of a molecular base (that is a neutral compound, not an ion!) and a salt of the conjugate acid of that molecular base should you select to prepare a buffer solution that would maintain a pH of 9.00? For full credit, explain
What differences might you expect in the comparative solubility of each of them in lipids? WHY?
what is the density of sample of ammonia gas if the pressure is 705mmHg and the temperature is 63.0 degrees C?
What is the theoretical yield of aluminum oxide if 1.60 mol of aluminum metal is exposed to 1.50 mol of oxygen?
An evaluation of R was performed, following the procedure described in this module. The barometric pressure was 736 torr, the temperature was 295k and volume of hydrogen gas collected was 35.6 mL. The calculated value of R was 82.1 mL atm K^-1 mol..
