This is the Sabatier process and is usually in need of high temperature and a metallic catalyst. So, balanced equation.
CO2 + 4H2 -> CH4 + 2H2O
As said, hydrogen is in excess, so CO2 is limiting and drives the reaction. One to one
36.6 moles CO2 (1 mole CH4/1 mole CO2)
= 36.6 moles CH4 produced in this reaction
-------------------------------------------------------
This is the Sabatier reaction or Sabatier process (the reaction of hydrogen with carbon dioxide at elevated temperatures and pressures in the presence of a nickel catalyst to produce methane and water) CO2 + 4H2 → CH4 + 2H2O
The hydrogen is required both to react with the carbon and the oxygen and all of this must be accounted for to produce the 76.6 moles of water. From the equation 4 moles of hydrogen reacts with 1 mole of carbon dioxide ot produce 2 moles of water. The production of 76.6 moles of water requires 153.2 moles of hydrogen.
48,1 moles Methane is equivalent to 48,1 moles carbon dioxide. If the reaction actually happen is a different story. It will be highly endothermic, that's for sure.
CO2+4H2 = CH4 + 2H20 (Balanced)
82.6 Moles.
The Ratio is 1 Mol CH4 over 1 Mol CO2.
So...
82.6 Mol CO2 * 1 Mol CH4/1 Mol CO2= 82.6 Moles of CH4
Use dimensional analysis:
(85.1 mol CO2)(1 mol CH4 / 1 mol CO2) = 85.1 mol CH4
Equation.
CO2 + H2 - CO + H2O
all one to one, so you need 53.6 moles of hydrogen gas
Q: How many moles of hydrogen gas would be needed to react with excess carbon dioxide to produce 53.6 moles of water vapor?
59.6 moles of methane are produced.
84,2 moles hydrogen are needed.
The gram molecular mass of hexane is 86.18. Therefore, 25.0 g of hexane constitute 25.0/86.18 or 0.290 moles. Each mole of hexane contains six carbon atoms and therefore will produce six molecules of carbon dioxide by burning in an excess of oxygen. 6 X 0.290 = 1.74 moles of carbon dioxide. The gram molecular mass of carbon dioxide is 44.00. Therefore, the mass of carbon dioxide produced will be 1.74 X 44.00 or 76.6 grams of carbon dioxide, to the justified number of significant digits.
Carbon dioxide is a colourless odourless gas made from a carbon atom covalently bonded to two oxygen atoms. Carbon dioxide is needed by plants for photosynthesis and it is produced as a waste product in respiration. Excess carbon dioxide may dissolve in sea water to produce carbonates. However, at present some scientists are concerned that too much carbon dioxide gas is getting into the atmosphere as a result of burning fossil fuels and this may be causing global warming.
None; everyone knows moles need dirt to live. Wat r u, stupid?
When carbon dioxide is added to water containing sodium hydroxide carbonate ions are formed but the excess of carbon dioxide produces bicarbonate ions on evaporation a mixture of sodium carbonate and sodium bicarbonate is obtained.
Hydrocarbons contain (ideally) hydrogen and carbon. When they are burned the hydrogen reacts with oxygen from the atmosphere to produce water H2O (usually steam) and the carbon reacts with more oxygen to produce carbon dioxide CO2. Both these processes release a lot of heat (they are exothermic) and the heat is often used to drive a heat engine, which could be a petrol or diesel engine or a gas turbine. The heat can also be used to turn water into steam which is used in a steam turbine, another type of heat engine. Hydrogen, carbon and oxygen have atomic weights of 1, 12 and 16. A hydrocarbon fuel like gasoline has approximately two hydrogen atoms for each carbon atom. 1 kg of fuel contains about 80% carbon and the molecular weight is about 14. Burning brings in two atoms of oxygen for each carbon atom, and one more atom of oxygen for the two hydrogen atoms. That means that 14 kg of fuel uses approximately 48 kg of oxygen to produce 44 kg of CO2 plus 18 kg of water. The above is an approximate estimate of the principles involved, but is useful as a guide for the hydrocarbon fuels used in vehicles. One kg of fuel gives rise to approximately 3 kg of carbon dioxide. A light gas like methane CH4 has proportionally more hydrogen, so 1 kg of fuel contains exactly 75% carbon, so the amount of carbon dioxide produced by burning is slightly less. Gas is seen as a 'clean' fuel but it is only slightly cleaner than oil fuels, because 100 lb of methane still contains 75 lb of carbon.
Carbon Dioxide & Water, Complete burning with excess of oxygen gives out Carbon Dioxide(CO2) + Water , While incomplete burning with limited amount of oxygen gives out Carbon monoxide (CO) + Water
The CO2 reacts with the H2O to create H2CO3 (Carbonic acid) Carbon dioxide + Water ---> Carbonic acid ----->Bicarbonate ion---> Hydrogen ion

Your body is an engine that uses fuel (food) to produce energy for you to do exercise. The fuel contains carbon from the carbohydrates you eat, and the body uses oxygen from the air to do a chemical reaction that combines the carbon with the oxygen to produce energy plus carbon dioxide. If you do exercise, you use more fuel and more oxygen, and you produce more carbon dioxide. The body has sensors that detect excess carbon dioxide in the blood, and they make you breathe faster to get rid of it.
carbon dioxide
CO2 + H2 -> CO + H2O one to one here 30.6 moles H2O (1 mole H2/1 mole H2O) = 30.6 moles Hydrogen gas needed
carbon monoxide?
Oxygen in excess: carbon dioxide is obtained.Not sufficient oxygen: carbon monoxide is obtained.
The oceans are becoming more acidic, harming coral and shellfish which are thus unable to produce strong shells.
When carbon dioxide is passes into lime water (a solution of calcium hydroxide) an insoluble precipitate of calcium carbonate is produced this is composed of tiny particles that cause the milkiness.Ca(OH)2 +CO2 -> CaCO3 +H2OWhen excess carbon dioxide is passed in this produces some carbonic acid, H2CO3 that reacts with the calcium carbonate to produce soluble calcium hydrogen carbonate, (calcium bicarbonate).CO2 +H2O -> H2CO3H2CO3 + CaCO3 -> Ca(HCO3)2
