CaH2 + 2H2O → Ca(OH)2 + H2
The calcium hydride and hydrogen are on a 1:1 molar ratio.
Therefore the number of moles of calcium hydride = number of moles of hydrogen, 0.44 mol

When metal reacts with nitric acid hydrogen is not produced why?
It is so because nitric acid is a very strong oxidising agent and as according to oxidation, it says loss of hydrogen is very important.... Thus, hydrogen is not produced. :)
Why is water produced when hydrogen is burned?
The combustion of hydrogen requires oxygen, which is supplied by the surrounding air. When hydrogen is combusted, it reacts with oxygen in the equation: 2H2 + O2 --> 2H2O with water (H2O) being the product
How does combining hydrogen and oxygen to create water relate to law of conservation of mass?
The mass of hydrogen and oxygen in the reactants is the same as the mass of the water produced. The balanced chemical equation for this reaction is 2H2 + O2 --> 2H2O. Notice that the numbers of hydrogen and oxygen atoms are the same on both sides of the equation.
How many moles of hydrogen iodide are produced from 1 mole of iodine?
The balanced equation for the reaction between Iodine and Hydrogen is: H2 + I2 --> 2HI The ratio of I2 to HI is 1:2 Therefore 1 mole of Iodine can form a maximum of 2 moles of Hydrogen Iodide
How is hydrogen made?
Most hydrogen is produced by electrolysis of water.
How many moles of hydrogen gas H2 is produced if 20.0 mol of Zn are added to hydrochloric acid HCl according to the equation Zn plus 2HCl --- ZnCl2 plus H2?
20,1588 grams of hydrogen
Do all reactions produce the same amount of hydrogen?
No. The amount of hydrogen produced is dependent on the amount of hydrogen in the reactants. Refer to the following examples. Notice that each equation is balanced so that there are the same numbers of each element on both sides of the equation. 2Na + 2H2O --> 2NaOH + H2 2Al + 3H2O(g) --> Al2O3 + 3H2 2H2O + electricity --> 2H2 + O2
What are some chemical equations on hydrogen?
hydrogen gas is produced through chemical reactions like: Mg+H2SO4=H2+MgSO4 The general equation is : metal + acids = hydrogen + salt.

What is the balanced equation for Liquid water is produced when hydrogen gas and oxygen gas combine?
H2o 2h2 + o2 = 2h2o

According to Bohr's model of the hydrogen atom how is hydrogen's emission spectrum produced?
it is produced when an electron from a higher energy orbit drops down to a lower level of energy orbit.

What is produced when hydrogen and oxygen react together?
Hydrogen and oxygen can react to produce water or hydrogen peroxide. Hydrogen peroxide is produced by a complicated process, but the overall equation is H2 + O2 ---> H2O2. Water is produced by the reaction of 2H2 + O2 --->2H2O.
What is the equation of magnesium chloride and sulfuric acid which gas is produced?
MgCl2 + H2SO4 ---> MgSO4 + 2HCl yield magnesium sulfate plus hydrogen chloride(gaz)
What produces hydrogen gas?
Well if you put magnesium with hydrochloric acid, the magnesium reacts with it and creates hydrogen and magnesium chloride. Here is the word equation... Magnesium + Hydrochloric acid --> Magnesium chloride + Hydrogen
