Hydrogen itself does not generate electricity, but it can be used to generate electricity in at least two ways. First, as a combustible substance, hydrogen could be used as a fuel source for an electric generator. This process is not the most efficient means to produce electricity with hydrogen, because the conversion of mechanical energy to electricity always results in a (typically) pretty significant loss of power.
The most common social association of hydrogen and producing power these days involves a fuel cell, where hydrogen is the fuel, and the air provides the oxidant (oxygen). A fuel cell sparks a reaction between the hydrogen and the oxidant by means of a catalyst (usually a pricey metal like platinum), and electricity is produced. About half of the energy potential is lost as heat, so this process is about 50% efficient.
Interesting side note. Diesel generators can be up to 45% efficient (possibly as high as 55%). I have no idea if a hydrogen generator could be nearly as efficient burning just hydrogen. My instinct is definitely no, based only on the assumption that diesel's high efficiency comes from the high compression design as compared to a gas generator. But... it would be interesting to know if it would be physically possible to make an electric generator that burns hydrogen as efficient or more efficient than the current crop of fuel cells ;-D.
The hydrogen in water is locked into a very stable molecule consisting of two Oxygen atoms and four Hydrogen. In order to break that bond, energy (for example, an electric current) must be introduced. Free hydrogen is not bound to anything.
Four oxygen molecules are produced from the splitting of two molecules of water. This is because for every two molecules of water that split, one molecule of O2 is produced according to the balanced equation shown.
This substance cannot be water, because passing an electric current through water, in a process called electrolysis, produces hydrogen and oxygen gas, not oxygen and sulfur.
There is only one product - water. Hydrogen burns in the oxygen in air to form hydrogen oxide or water vapour. 2H2 (g) + O2 (g) = 2H20 (g)
Hydrogen is the most abundant element in the universe, and the third-most common element on the Earth's surface. It can be produced, among other ways, by splitting water molecules (which as a side-effect, also produces oxygen gas) in a process known as water electrolysis; by exposing metals to certain acids; or by breaking down hydrocarbons, including those found in urine or natural gas.
Hydrogen and oxygen gases are produced from splitting water.
Splitting water results in oxygen and hydrogen. The water element is separated into two hydrogen atoms and one oxygen atom.
The element that produces oxygen in water is hydrogen, through the process of electrolysis. When electricity passes through water, it splits into hydrogen and oxygen gas. This is how oxygen is generated from water.
No. It is endothermic as it requires energy.
The splitting of water molecules into hydrogen and oxygen molecules is an example of a chemical reaction known as electrolysis. This process involves passing an electric current through water to separate it into its constituent elements, hydrogen and oxygen.
no, it is chemical.

The reaction between oxygen and hydrogen produce water.
Water on electrolysis (splitting) gives elements Hydrogen and oxygen in a fixed proportion
The process that produces oxygen gas in an oxygen cell is electrolysis. In this process, an electrical current is passed through water (H2O), splitting it into oxygen gas (O2) and hydrogen gas (H2). This method is commonly used in devices like fuel cells and electrolyzers for various applications.
This is the word equation for the electrolysis of water; splitting it apart into its component elements.
A water electrolysis catalyst helps to speed up the splitting of water into hydrogen and oxygen by lowering the energy needed for the reaction to occur. It acts as a facilitator, allowing the process to happen more efficiently and quickly.
