To produce 1 mole of methane (CH4), you need 2 moles of hydrogen (H2). Since 22.4 L of hydrogen is equivalent to 1 mole at standard temperature and pressure (STP), you would need 44.8 L of hydrogen to produce 1 mole of methane. Therefore, to produce 20 L of methane, you would need 896 L of hydrogen.
By litter I am assuming you mean "Manure". all Manure as it decomposes releases a gas called Methane. Methane can be burnt to create heat and hence - boil water and in turn the steam used to drive a turbine and create electricity... in exactly the same way as a regular coal fired power station works. If you are talking about creating electricity for lighting a home, rather than go to the complexity of creating a power plant to run light bulbs, a simpler option is to burn the methane using a mantle (as used in camping LPG lanterns) to produce a light source. In order to collect the methane from manure, a sealed tank is required. The manure needs to be held in a gas tight chamber, and provision needed for removing moisture and adding new material. This needs to be incorporated so that more manure can be added and waste "spent" manure removed and recycled. (as garden fertiliser.) This chamber also needs to have a weighted cover to provide positive gas pressure. This will allow gas to flow through pipes to the electricity plant or into lighting fixtures. Methane is a very bad green house gas, burning turns it into less volatile carbon dioxide extracts otherwise wasted energy. You can find drawings for creating a manure chamber in the excellent book entitled "Self Sufficiency" by John Seymour.
Because the machinery needed to convert cow feces into energy is a bit costly. Oh it has energy all right, but it's just not something that has caught on popularity yet, since we are still suckling at the nipples of the oil and gas giants, in a manner of speaking.
what is the mass in grams of oxygen, is needed to complete combustion of 6 L of methane?
The balanced equation for the reaction between hydrogen gas (H2) and carbon disulfide (CS2) to produce methane (CH4) is: 4H2 + CS2 → 4H2S + CH4. This means that for every 4 moles of hydrogen gas, 1 mole of methane is produced. Since 1 mole of any gas at STP occupies 22.4 liters, you would need 5.6 liters of hydrogen gas to produce 2.5 liters of methane.
To react completely with one molecule of methane (CH4), two molecules of oxygen (O2) are needed. This is because the balanced chemical equation for the combustion of methane is CH4 + 2O2 → CO2 + 2H2O. Each molecule of methane requires two molecules of oxygen to form carbon dioxide and water.
Approximately 3,000 kilograms of bark is needed to make 120 kilograms of paclitaxel, as the yield of paclitaxel from the bark of the Pacific yew tree is around 0.04-0.05%.
The needed mass of oxygen is 16 g.
56 kilograms
Methane requires a source of ignition, like a flame, to initiate the combustion process. This is because methane needs to reach its ignition temperature before it can react with oxygen in the air to produce a flame. In the absence of a spark or flame, the energy needed to overcome the activation energy barrier is not present to start the reaction.
Approximately 770 kilograms of coking coal are needed to produce one ton of steel through the traditional blast furnace method. The coking coal is used as a fuel and as a reducing agent in the steelmaking process, where it helps convert iron ore into molten iron in the blast furnace.
You need about 4 lb (2 kg)kilograms to make a can of soda.
