Kc for the reaction CO2 + H2--------H2O + CO is 1.6 at about 990 C. Calculate the number of moles of carbon dioxide in the final equilibrium system obtained by initially adding 1.00 mol of H2, 2.00 moles of CO2, 0.750 mol of H20, and 1.00 mol of CO to a 5.00 L reactor at 990 C.
Supercooled (metastable) water vapor commonly occurs in the atmosphere if dust particles are not present to begin condensation of the liquid.Sometimes small particles,such as tiny crystals of silver iodide
what the final orbital should be ? would you expect Rh to be paramagnetic or diamagnetic? Explain your answer to each question? please explain in details so its easy for me to understand this.
A 50ml aliquot of this sample, treated with pyrophosphate to mask Fe and Cr, required 26.24ml of 0.05831 M EDTA to reach the endpoint. A second 60ml aliquot was treated with hexamethylenetetra to mask the Cr.
Nitrogen gas when combined with hydrogen gas forms ammonia gas according to the following equation N2(g) + 3H2(g) = 2NH3(g). Delta H(rxn)=-56 kJ. The delta H(rxn) was determined using Hess's Law and the following three related reactions:

How much heat (in kJ) is released when 15.0 L of CO at 85 degrees C and 112 kPa reacts with 18.5 L of H2 at 75 degrees C and 744 torr?
How many hydrogens are in C6H?NO3, which has 1 ring and 4 double bonds? How many hydrogens are in C13H?N, which has 4 rings and 6 double bonds?
You should practice writing valid (balanced equations) for alkanes -- oxidation reactions (combustion reactions with O2) and halogenation reactions (reactions with halogen gasses, such as Br2).
calculate the moles of CO2 you would theoretically expect from 0.253 grams of an alka-seltzer tablet at 721. torr and 291. K.
What is the partial pressure of N2(g) (in atm) in a container filled with 0.1 mol N2(g), 0.2 mol O2(g) and 0.35 mol CH4(g) when the total pressure in the container is 5.0 atm
