Carbon fuels of which petrol is one when used as a fuel will breakdown and give off carbon dioxide, thus releasing the stored energy. The carbon molecules combine with oxygen needed for ignition and the resulting excess becomes CO2 (a gas)
When Hydrogen is used as a fuel igniting with oxygen the resulting by product is mainly H2O (water and water vapour)
Adding sodium hydride to ethanol would produce sodium ethoxide and hydrogen gas. Sodium hydride is a strong base and will react with ethanol to form the ethoxide salt and release hydrogen gas as a byproduct.
Your equation is properly balanced so for every mole of hydrogen produced it takes 2moles of sodium; therefore to produce 4.0 mol of hydrogen it would take at least 8.0 mol of sodium if the reaction were 100 % efficient.
That depends on what chemicals were mixed in order to produce the hydrogen gas. For example, if it was the metal magnesium (Mg), and the acid hydrochloric acid (HCl), then the equation would be Mg(s) + 2HCl(aq) -- > MgCl2(aq) + H2(g). Please note that the 2 after MgCl is supposed to be a subscript, as is the 2 after hydrogen. We are having difficulties with the subscripts and superscripts right now.
One mole of CO2 requires one mole of O2 to produce during combustion of carbon-containing compounds.
The amount of pollution a truck produces depends on factors like its age, engine type, and fuel efficiency. On average, a diesel truck can emit about 4.8 metric tons of carbon dioxide per year, along with other pollutants like nitrogen oxides and particulate matter. Electric trucks have zero tailpipe emissions, significantly reducing pollution.
well its cause they didn't produce it
Hydrogen is the simplest element in the universe. Combining hydrogen and oxygen in a fuel cell would produce energy without pollution.
New fueling stations that can handle hydrogen would have to be built.
hydrogenA2:Coal is the fuel that produces the least pollution among the choices. Hydrogen would be the least polluting except for the reality that hydrogen is produced by burning coal to produce electricity to electrolyse water. Only if the electricity used to produce the hydrogen were produced by hydro, wind or solar, would hydrogen be less polluting than coal.
To produce 1 mol of water, 2 mol of hydrogen is needed. Therefore, to produce 7.5 mol of water, you would need 15 mol of hydrogen.
The closest to a non-polluting gas would be hydrogen as the principle combustion product would be water. ANy flammable gas with carbon, sulfur or nitrogen would produce contaminants. The gas would have to be combusted in a low temperature environment like a fuel cell to avoid the formation of nitrogen oxides in the combustion chamber. If a high temperature system (internal combustion engine) is considered the combustion air would have to be nitrogen free - pure oxygen or an inert gas/nitrogen free/oxygen mix
The reaction is 2H2 + O2-> 2H2O So, both the molar and volume ratios would be 2 moles(liters) of hydrogen to every mole(liter) of oxygen. By weight, the ratio would be about 8 grams of oxygen to every gram of hydrogen
No. The sun's energy comes from the nuclear fusion of hydrogen, not combustion. In this reaction hydrogen atoms fuse with one another to form helium atoms. The fusion of hydrogen yields about 4.5 million times more energy than you would get from burning the same amount.
1 mole
To produce 1 mole of water, you need 2 moles of hydrogen. Therefore, to produce 7.4 moles of water, you would need 2 * 7.4 = 14.8 moles of hydrogen.
Other combustion reactions that would produce carbon dioxide and water vapor include burning natural gas (methane), gasoline, wood, and propane. In each of these reactions, the fuel combines with oxygen to undergo combustion, resulting in the production of carbon dioxide and water vapor as byproducts.
It effects them because when the hydrogen bonds form the pollution will also go into the formation too.
