What volume of hydrogen gas - at 756 mm Hg and 22 degrees Celsius - is  required to synthesize 6.92 grams of methanol?    Methanol's reaction is   CO + 2 H2 = CH3OH

If 0.25 L of gaseous CH4 is burned at STP, what volume of O2 is required for complete combustion?

If 77.4 grams of carbonic acid are sealed in a 2.00 L soda bottle at room temperature (298 K) and decompose completely via the equation below, what would be the final pressure of carbon dioxide (in atm) assuming it had the full 2.00 L in which to expand? H₂CO₃(aq) → H₂O(l) + CO₂(g)

Explain Boyle's law and Avogadro's hypothesis and their use in the hydrocarbon industry.

27.   1.20 g of a gas compound containing C, H and S in 2.10 L. flask has the pressure of 108  mmHg at the temperature of 25oC .   1.00 g of the compound is burned in pure oxygen produces 2.24 g CO2 and 0.551 g H2O.  0.480 g of the compound produces 0.313 g SO2.  Calculate the molecular formula of the compound. C = 12.01 g/mole , H = 1.00 g/mole, S = 32.07 g/mole,  O = 16.00 g/mole  a.CH3S b.CHS c.C2H3S2 d.C5H6S

for this question. Sodium metal reacts with water to produce hydrogen gas according to the following equation: 2Na(s) + 2H,0(1)→2NAOH(aq) + H2(g) The product gas, H2, is collected over water at a temperature of 20 °C and a pressure of 759 mm Hg. If the wet H, mol. The vapor gas formed occupies a volume of 9.89 L, the number of moles of Na reacted was pressure of water is 17.5 mm Hg at 20 °C.

A gas at 5.00 atm pressure was stored in a tank during the winter at 5.0 °C.  During the summer, the temperature in the storage area reached 25.3 °C.  What was the pressure in the gas tank then?

determine 1) the limiting reagent, 2) the moles of each reactant left over, and 3) volume (in L) of any gaseous products at STP.        Combustion of 9.112 X 1023 molecules of methane (CH4) with 75.0 L of O2 at 1.0 atm and 299.15 K (assume any water produced is liquid).

Methanol is synthesized by the reaction of CO2 and H2 as seen in the reaction  CO + 2 H2 = CH3OH  What volume of hydrogen gas, at 756 mm Hg and 22 degrees Celsius, is required to synthesize 6.92 grams of methanol?
