From what elements is ammonia produced?
a reaction with nitrogen and hydrogen
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.
What happens if magnesium is added to hydrochloric acid is a singlereplacement reaction?
Yes, when magnesium reacts with hydrochloric acid it is a single replacement reaction. The same is true for nearly all cases of a reaction between an acid and a metal.
Is hydrogen a reactants?
Hydrogen can be a reactant or a product, it depends on the chemical reaction. Anything to the left of the arrow is consumed by the reaction and is thus a reactant, so hydrogen is a reactant in the reaction O2 + 2H2 -> 2H2O. A product is on the right of the arrow and is produced by the reaction, so hydrogen is a product in the reaction Zn + 2HCl -> ZnCl2 + H2
What causes potassium to catch fire?
Let's look at the equation for the reaction of potassium and water: Potassium + water --> potassium hydroxide + hydrogen The reaction is fast and generates sufficient heat (it is exothermic) for the hydrogen gas produced to react with oxygen in the air. The presence of potassium gives the flame a lilac colour as the hydrogen burns. In comparison, lithium and sodium are less reactive so the reactions are slower and produce less heat so the hydrogen gas produced does not ignite. So, the potassium does not burn, the hydrogen does!
What volume of hydrogen gas is produced at stp as sulfuric acid reacts with 120 g of metallic calcium in a single replacement reaction?
The chemical reaction is:Ca + H2SO4 = CaSO4 + H2The volume of released hydrogen is 66,6 L.
What is produced when hydrogen reacts with water?
There is no reaction.

Can helium be turned into hydrogen to produce energy?
No, energy is produced by the opposite reaction, hydrogen to helium

What gas is produced by sodium?
After the violent reaction of sodium with water hydrogen is released.
How is hydrogen peroxide produced in a cell?
Catalase is an enzyme that speeds up the reaction.
Solar energy is produced by the fusion of what?
Hydrogen (essentially a proton-proton reaction)
Does the removal of hydrogen gas as it is produced shift the reaction to the left or the right?
Right
What is produced from the splitting water during the light-dependent reactions What is this process called?
During the light dependent reaction, it produced Oxygen and Hydrogen..hope that can help...:D
