How can the theoretical yield of carbon disulfide be calculated when 120 g of methane is reacted with an equal mass of sulfur?

CH4 + 4S --> CS2 + 2H2S
120 g CH4 / 16.04 g/mol = 7.48 mol CH4
120 g S / 32.06 g/mol = 3.74 mol S
1 mol CH4 requires 4x1 mol S
7.48 mol CH4 requires 29.92 mol S
S is limiting
3.74 mol S will yield 3.74 / 4 or 0.935 mol CS2
0.935 mol CS2 x 76.1 g/mol = 71.2 g CS2 theoretical yield

When methane is burned in a lime kiln why are the wast gages carbon dioxide and nitrogen?
the oxygen in the air combines with the methane making carbon dioxide and leaving un reacted nitrogen from the air.
How is hydrogen processed?
One method for creating hydrogen is through methane reforming. Natural gas (which is mostly methane) is reacted, sometimes with steam, sometimes with oxygen. This natural gas degrades into hydrogen, carbon dioxide and carbon monoxide in varying amounts. This reaction takes place above 500 C and is used industrially to create hydrogen.
What happens when fluorine is reacted with potassium chloride?
nothing
What is the liquid that are produce effervescence when reacted with sodium carbonate solution?
HCOOH
How many moles of N2 are produced by the decomposition of 2.88 mol of sodium azide?
2NaN3 --> 2Na + 3N22.88 mol of NaN3 reacted * (3 mol of N2 produced / 2 mol of NaN3 reacted) =4.32 mol of N2
Which alkane do you suggest for preparation of toluene?
Methane could be used used for preparation of toluene but not directly. First, methane is reacted with chlorine to give chloromethane and that chloromethane is reacted with AlCl3 to form CH3+ and AlCl4- . This is reacted with Benzene(C6H6). This yields toluene as CH3+ replaces a hydrogen from Benzene.
What happened to ammonia and methane in earth's early atmosphere?
reacted out with oxygen as oxygen levels rose.
Why methane is exothermic?
because its simply a hydrocarbon. Hydrocarbons cannot produce and endothermic energy when reacted.
If in the previous problem only 25.9 grams of water vapor were formed how much methane actually reacted with oxygen?
Methane and oxygen react according to the equation:CH4 + 2O2 -->CO2 + 2H2O Thus 1 mole of methane produces 2 moles of water. 25.9 g of water is 25.9/18 moles = 1.44 moles.So we must have started with 0.72 moles of methane, which is 0.72 x 16 g= 11.51 g of methane.
What is the theoretical percent yield?
Percent yield is a term that compares the amount actually produced in a chemical reaction versus how much could have been produced had all the reactants reacted fully. Theoretical percent yield is always 100%, because theoretically, all of the reactants reacted.
When methane is burned in a lime kiln why are the wast gages carbon dioxide and nitrogen?
the oxygen in the air combines with the methane making carbon dioxide and leaving un reacted nitrogen from the air.
What is made when methane and air are reacted?
methane rapidly combines with oxygen to form carbon dioxide and water, releasing lots of heat. it's called combustion.-------------------------------------------------------------------------CH4 + 2O2 = CO2 + 2H2O + heat
Calculate the theoretical yield of calcium chloride expected for this reaction if 0.80 mol of calcium hydroxide is reacted with excess hydrochloric acid.?
0.80
How many moles of carbon dioxide are formed from 14 moles of methane?
When methane undergoes complete combustion, the equation for the reaction is CH4 + 2 O2 -> CO2 + 2 H2O. This shows that the number of moles of carbon dioxide formed are the same as the number of moles of methane reacted, so that 14 moles of carbon dioxide will be formed from 14 moles of methane.
What is the theoretical yield of magnesium chloride if 50.6 grams sample of magnesium hydroxide is reacted with 45.0 grams of hydrochloric acid?
Magnesium chloride: 81,95 g are obtained.
What is the theoretical mass of xenon tetrafluoride that should form when 130 G of xenon is reacted with 100 G of F2?
The answer is 205 grams. You can easily convert that to SI units.
What is the dependent and independent variable in an experiment to find the gas constant where you change the mass of Mg reacted with HCl to form different number of moles of H2 gas?
co2 and oxygen even a little methane
