When hydrogen is passed over hot tungsten oxide?
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.
Write the chemical equation for the decomposition of water?
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?
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.
Can be decomposed by electricity into the elements hydrogen and oxygen a chemical?
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.
What is the chemical formula when nitrogen gas reacts with hydrogen gas?
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 hydrogen is passed over hot tungsten oxide?
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.

How much hydrogen gas is produced when steam is passed over hot iron?
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.
What type of chemical reaction takes place when a electric current is passed through water and write chemical equation for the same?
This is an electrolysis process:2 H2O-------------2 H2 + O2
When hydrogen gas passed over heated cupric oxide?
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.
When few pieces of marble is dropped in dilute hydrochloric acid the evolved gas passed through lime water what change would be observed in lime water so what will be the balanced chemical equation?
The chemical equation is:Ca(OH)2 + CO2 = CaCO3 + H2O
What happens when hydrogen reacts with copper oxide?
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.
When hydrogen is passed over copper oxide copper and water are formed what is the balanced equation for this and which of the chemicals are elements compounds reactants products metals and non-metals?
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.
What is a metal that glows when electricity is passed through it?
Phosphorus is a non-metal that glows when electricity is passed through it. It emits a light known as phosphorescence.
Can be decomposed by electricity into the elements hydrogen and oxygen a chemical?
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.
What is the chemical formula when nitrogen gas reacts with hydrogen gas?
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.
Can water be broken down by chemical?
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.
