The reaction of methane and water is a way to prepare hydrogen according to CH4 (g) + H2O = Co2 (g) + H2 (g) a) If 995 g of CH4 reacts with 2510 g of water, how many moles of reactants and products are there when the reaction is finished? Identify the limiting reagent in the reaction. b) If only 228 g of H2 are produced what is the % yield of gas?
A 0.2254 g sample of naphthalene (C8H10, 128.16 g/mol) was burned in a bomb calorimeter with a heat capacity of 2.18 kJ/K, and the temperature increased by 4.16°C. What is the molar enthalpy of combustion for this compound
The enthalpies of formation of oxalic acid in the solid and aqueous phases are -826.8 and -818.8 kJ/mol, respectively. The heat capacity of water is 4.184 J/g*K. Ignore the heat capacity of oxalic acid.
Devise a plan to calculate the mass of air that was contained in the clean dry stoppered flask, using the mass measurements you will make during the experiment. the calculation will require another density value besides the density of air.

Calculate the work done (in Joules) when 33.3g of tin dissolves in excess acid at 1.04 atm and 22 degrees C. Assume ideal gas behavior.
How would the ground-state energy levels of X and H compare and would the energy of an electron in the n = 2 level of H be higher or lower than that of an electron in the n = 2 level of X? Explain your answer.
What is the limiting reagent? Show the reasoning b) Calculate the theoretical yield in milliliters of the butene produced at 740 mm and 25 C when it is collected over water.R=0.0821
How could you use a conductometric titration to determine the molarity of either reacting solutions, assuming you knew the concentration of one
What would the internal energy of the gas be if it were compressed to .10 m^3 while the pressure was held constant?
An industrial wastewater contains 2000 mg/L of total Ammonia as N, 490 mg/L of total Ni and has no inorganic carbon. The PH = 2.8. Using the diagram calculate to what pH the waste must be adjusted to so that the total Ni concentration is 1 mg/L.
a sample of riboflavin has a molar absorptivity of 1.67 x 10^3 L(mol x cm). What is the concentration of a solution with an absorbance of 0.484? The pathlength is 1.00cm.
A flexible container at an initial volume of 6.13 L contains 8.51 mol of gas. More gas is then added to the container until it reaches a final volume of 18.5 L. Assuming the pressure and temperature of the gas remain constant, calculate the number..
