2H2 + O2 ---> 2H2O
3.5 mole of hydrogen will produce 3.5 mole of water.
3,75 moles hydrogen
7.4 mol of H2
There are a number of ways of preparing Hydrogen. One is the electrolysis of water. Another would be to add a metal to an acid. As an example Magnesium and Hydrochloric Acid would produce hydrogen. Mg + 2HCl -----> MgCl2 + H2
if hydrogen has to be produced from hot water then magnesium produces more in a short time because it is more reactive towards water but if water is pour on red hot iron then it produces more.
Then the water would not exist.
3,75 moles hydrogen
7.4 mol of H2
the answer would be 5.9
Sodium metal is very reactive and would explode when in contact with water and produce hydrogen gas.
Neither. A non-metal element has no charge, which would be required for attraction.
As each water molecule contains one atom of Oxygen and two atoms of Hydrogen you would expect electrolysis of water to produce twice as much Hydrogen as Oxygen.

Hydrogen and oxygen are the reactants and water is the product.
It would take 1 ton of water to create 1 ton of steam.
hydrogenA2:Coal is the fuel that produces the least pollution among the choices. Hydrogen would be the least polluting except for the reality that hydrogen is produced by burning coal to produce electricity to electrolyse water. Only if the electricity used to produce the hydrogen were produced by hydro, wind or solar, would hydrogen be less polluting than coal.

The Elements Hydrogen (H) reacts with Oxygen (O) to produce Water.Or as a chemist would say ... 2H2 + O2 = 2H2O
