How is helium naturally produced in the stars?
It is produced from hydrogen, by nuclear fusion.
Why does the hydrogen gas produced in laboratory not glow and emit radiations?
Hydrogen is not radioactive.
What gas is produced when metals react with water or acid?
If a gas is produced it is hydrogen (H2)2H+(from acid) + 2e-(from metal) --> H2
What gas is produced with nickel and water?
Hydrogen
What is the difference between sunlight produced spectrum and hydrogen gas produced spectrum?
The spectrum of sunlight is continuous while for hydrogen is line spectrum (discontinuous)
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.
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
What is the balanced equation for Liquid water is produced when hydrogen gas and oxygen gas combine?
H2o 2h2 + o2 = 2h2o
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.
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 happens to the pH As the hydrogen ion concentration increases?
as the pH increases in acids, the acids lose their ability to ionise in water, so less hydrogen ions are produced. so stronger acids, like hydrochloric acid with a low pH, produce more hydrogen ions than weaker acids, like ethanoic acid with a high pH.
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
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
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
Is hydrogen a bio-fuel?
No. Hydrogen is not derived from biological sources. It is produced by electrolysis of water.
What is produced by the nuclear fusion of hydrogen?
Helium is produced.
