Does the reaction that separates water into hydrogen and oxygen absorb or release energy?
Endothermic reaction is the breakdown of water into hydrogen and oxygen and this cause for energy to be absorbed
What is the reaction taking place as the hydrogen burns?
Water is formed when hydrogen gas burns (reacts) with oxygen (from air) 2 H2(g) + O2(g) --> 2H2O(l)
Why doesn't Saturn catch fire when it lightnings?
Although the atmosphere of Saturn is mostly hydrogen, that hydrogen cannot burn as Saturn's atmosphere has little or no oxygen. When hydrogen burns it is reacting with oxygen to form water.
What is pure water and write its chemical formula?
H2O A compound formed when hydrogen gas burns with oxygen.
Does the hydrogen on methane go when it becomes carbon dioxide?
Methane burns in oxygen and gets oxidised. Carbon is oxidised to carbon dioxide, hydrogen to water.
Why does hydrogen burns?
Hydrogen burns because the energy released from the H-O bonds it forms with water is greater than the energy required to break the H-H and O=O bonds in molecular oxygen and hydrogen. 2 H2 + O2 ---> 2 H2O
In the example of hydrogen plus oxygen water which type of reaction does this represent?
Hydrogen combining with oxygen to form water is an exothermic reaction, which is why hydrogen burns.
When hydrogen burns what compound does it make?
Water (H2O) is formed when hydrogen is burned by oxygen
Does oxygen and hydrogen explode when ignited?
Oxygen has a tremendously greater attraction for electrons than hydrogen does, so when hydrogen donates an electron to oxygen, there is a substantial release of energy. This energy appears in the form of heat, so the gases (hydrogen, oxygen, and water vapor which is the product of the reaction) will be very hot. Hot gases expand rapidly, hence, they explode.
Does the reaction that separates water into hydrogen and oxygen absorb or release energy?
Endothermic reaction is the breakdown of water into hydrogen and oxygen and this cause for energy to be absorbed
Who discovered the water can be us as gasoline?
No one, as it can't. They are developing an automobile that runs on water. It separates the hydrogen from the oxygen. The hydrogen burns.
What chemical product is made when hydrogen burns?
Hydrogen chloride (HCl). It is commonly known as hydrochloric acid.
The reaction in which hydrogen burns in oxygen to form water is an example of a?
double-displacement reaction
Will the energy produced on combustion of hydrogen be more than the energy used for separation of hydrogen from water through electrolysis?
In theory, the energy produced by creating four oxygen-hydrogen bonds after breaking two Oxygen-oxygen and hydrogen-hydrogen bonds in the reaction O2 + 2H2 -> 2H2O (hydrogen combustion in oxygen) is exactly the same than the energy needed to break four oxygen-hydrogen bonds to create two oxygen-oxygen and hydrogen-hydrogen bonds in the reaction 2H2O -> O2 + 2H2 (water electrolysis) However, you will always have great energy loss during electrolysis (an important part of your energy will be used to warm up your water) and in getting back your energy from your oxygen and hydrogen gas (a combustible battery or a motor will warm up too).
Does pure hydrogen burn?
Yes, Hydrogen burns in the presence of Oxygen to form the compound H2O, better known as water.
What molecule is oxidized and what kind of bond is formed when gaseous hydrogen burns in the presence of oxygen to form water?
hydrogen, polar
Is this true when one burns hydrogen with oxygen to make water two oxygen atoms go into each water molecule?
No. When making water by burning Hydrogen in Oxygen (a very explosive reaction) is that 2 atoms of Hydrogen and 1 atom of Oxygen join together to form 1 water molecular - H2O.
