When Hydrogen Is Passed Over Hot Tubgsten Oxide (WO3)
WO3 + 3H2 ----------------> 3H2O + W
When hydrogen is passed over hot tungsten oxide, it reacts with the oxygen in the tungsten oxide to form water vapor, leaving behind tungsten metal. This reaction is a reduction reaction where tungsten oxide is reduced to tungsten metal.
The chemical equation for the decomposition of water is: 2H2O -> 2H2 + O2. This reaction occurs when an electric current is passed through water, splitting it into its constituent elements, hydrogen and oxygen gas.
When hydrogen gas passed over heated cupric oxide, the hydrogen is oxidized and displaces copper from the copper oxide as metallic copper, because hydrogen is higher than copper in the electromotive series. Water vapor is also produced by the reaction.
Yes, water can be decomposed by electricity into the elements hydrogen and oxygen. This process is known as electrolysis, where an electric current is passed through water to separate it into its constituent elements.
Nitrogen and hydrogen react to form ammonia. This is the reaction in the Haber process, in which the gases are mixed at high pressure and moderately high temperature and passed over an iron catalyst.

When steam is passed over hot iron, the reaction produces iron oxide and hydrogen gas. The amount of hydrogen gas produced depends on the reaction conditions such as temperature, pressure, and quantity of iron. From the balanced chemical equation, for every mole of iron that reacts, one mole of hydrogen gas is produced.
This is an electrolysis process:2 H2O-------------2 H2 + O2
When hydrogen gas passed over heated cupric oxide, the hydrogen is oxidized and displaces copper from the copper oxide as metallic copper, because hydrogen is higher than copper in the electromotive series. Water vapor is also produced by the reaction.
The chemical equation is:Ca(OH)2 + CO2 = CaCO3 + H2O
When hydrogen reacts with copper oxide, it reduces the copper oxide to form copper metal and water. This is a redox reaction where hydrogen acts as a reducing agent and copper oxide is oxidized. The balanced chemical equation for this reaction is: 2H2 + CuO -> Cu + H2O.
Assuming it's copper(II) oxide, the equation for that reaction is: CuO + H2 --> H2O + Cu. Reactants: copper oxide and hydrogen gas. Products: Water and copper. Elements present: hydrogen, copper. Compounds present: copper oxide, water. Metals: copper. Non-metals: hydrogen.
Phosphorus is a non-metal that glows when electricity is passed through it. It emits a light known as phosphorescence.
Yes, water can be decomposed by electricity into the elements hydrogen and oxygen. This process is known as electrolysis, where an electric current is passed through water to separate it into its constituent elements.
Nitrogen and hydrogen react to form ammonia. This is the reaction in the Haber process, in which the gases are mixed at high pressure and moderately high temperature and passed over an iron catalyst.
Water can be broken down by the chemical process called electrolysis. An electrical current is passed through water with an electrolyte added to it. The electrical current breaks down the water into hydrogen and oxygen gas that bubble up from the electrodes in the water.
