What is the physical makeup of water H2O hydrogen and two part oxygen?

One water molecule consists of two Hydrogen atoms and one Oxygen atom.\n\nSet yourself up an experiment.\nYou need a known weight (mass) of a compound that will absorb water and water moisture.  When breathing out, let the expired air pass into the same environment as the absorbing compound.  Do this a number of times.  Then reweigh the absorbing compound.  The gain in mass of the absorbing compound will be due to he water in the expired air.

i dont know what is too difficult inthe question to understand it!!\nok to find out the formula of a binary compound whatu need to know essentially is the valency exhibited by an element in that compound\nlet us take water: constituted by hydrogen and oxygen\nvalency exhibited by hydrogen is always 1, and that exhibited by oxygen is 2\nthis implies that two atoms of hydrogen combine with one atom of oxygen and hence the formula of water is H2O

The polar nature of the water molecule is responsible for hydrogen bonding.

Thank you punnet pundit. I was thinking the same thing. \n\nWhen combining Hydrogen and Oxygen one will get water or hydrogen peroxide. Simple enough. But that's not all there is to it. Just mixing the two doesn't cut it. The mixture must first gain enough energy to react. This is called it's Activation Energy. Which is the amount of energy it needs to absorb in order to carry out a chemical reaction. In the case of water the reaction is spontaneous and once started will continue until there is no longer enough reactants to form products. \n\nIn the case of water the reaction is explosive and quite violent. Liquid Oxygen and Liquid Hydrogen are used in space ships, because the reaction is enough to give the rocket a signifigant amount of upward force. The product is steam really because the water is way above 212 degrees F. but if this is condensed onto something below that temperature you get pure water.\n\nHydrogen peroxide slowly over time can break down in light. That's all I really know about it.

Peroxide is H2O2. If it were in a clear bottle, that second oxygen would evaporate and it would become H20...water.

It's liquid hydrogen and oxygen.  I imagine they just make it in a factory by cooling down those gases to very low temperatures.

for one molecule of H2O, there will be one molecule of H2 and one molecule of O.\n\nfor one molecule of H2O, there will be two atoms of H and one atom of O.

Water is created by burning hydrogen.

Each molecule of hydrogen contains 2 hydrogen atoms (H2) and each molecule of water contains 2 hydrogen atoms.  So a mole of water contains a mole of hydrogen.  For the second part of your question, there are 6.02e23 molecules of H2O in a mole of H2O.  Each H2O molecule contains 3 atoms, so a mole of H2O has 3*6.02e23 = 18.06e23 atoms.\n\nAdditional comment:  When one says "a mole of hydrogen," what is normally meant is a mole of hydrogen gas, which is H2, not a mole of hydrogen atoms.

Water. Water contains two hydrogens and one oxygen. It's technical name should be dihydrogen monoxide, but we knew about water before chemistry was officially developed.

The number always comes after the element, so two hydrogen and one oxygen.\n\neg if you have a more complex compound like Sulphuric Acid,\nH2SO4 that would be 2 hydrogen, one sulphur (or Sulfur in the USA) and 4 Oxygen

No. It is a chemical compound. All rain water is a compound of two elements hydrogen and oxygen. The chemical formula for water is h2o - meaning two hydrogen atoms and one oxygen. Usually when rain becomes acid it has sulfur dioxide (another compound formed of sulfur and oxygen) and nitrogen oxide (yet another compound formed from the combination of the elements nitrogen and oxygen as well). These chemicals combine with the water to form sulphuric acid and nitric acid.

you'll have a mixture of hydrogen and oxygen

chemical symbols... here is an example\n\nH(g) + O(g) -> H2O(l)\n\nH is hydrogen(gas)\n\n+\n\nO is oxygen(gas\n\nproduct is water (liquid)

Not sure what you mean. \n\nHowever water is a compound made up from 2 atoms of hydrogen(H) and one atom of oxygen (O), hence H20. You cannot have water without either element, so yes oxygen is needed to make water.

number of moles of hydrogen is 0.2\n\namount of water is 2.4
