is 2h the same as h2?

H2 is molecular hydrogen.it is a molecule of hydrogen that consists of two hydrogen atoms bonded together by one single bond. 2H denotes two moles of elemental hydrogen.it should be noted that elemental hydrogen is not bonded to anything.

Recall that two hydrogen atoms bind to make a hydrogen molecule. The same can be said of one mole of any other substance where two atoms combine to make a simple molecule. A mole of oxygen atoms 16 grams while a mole of oxygen molecules is 32 grams.

1 mole of hydrogen gas contains 6. 02×1023 atoms. 1 molecule of hydrogen(H2) contains two atoms of hydrogen.
1129172
In this case, the periodic table tells us there is 1g of hydrogen per mole. We know that dihydrogen (H2) has 2 hydrogen atoms per molecule, so there will be 2 * 1g hydrogen per mole = 2g dihydrogen per mole.

There are 2 hydrogen atoms in 1 molecule of water. 1 mole of H2O contains 2 moles of H, and each mole of H contains 6.02x10^23 atoms of H.

H2 is a gas which forms when two hydrogen atoms bond together and become a hydrogen molecule. H2 is also called molecular hydrogen.It consists of two protons and two electrons. ... It is the antioxidant in 'hydrogen-rich' water. H2 is the smallest molecule in the universe.

A water molecule (formally known as dihydrogen monoxide) is composed of two hydrogen atoms and one oxygen atom. ... The actual reaction to make water is a bit more complicated: 2H2 + O2 = 2H2O + Energy.
1364098
Also 1 mole =22.4 L of gas at STP. So now 1 mole of H2 gas weighs equal to 2 grams.

H2 is a molecular formula; it represents a diatomic molecule of hydrogen, consisting of two atoms of the element that are chemically bonded together.
338666
Number of H atom in 1 mole H2 is 2×6.022 × 10^23 atom.

Two water molecules contain 4 hydrogen atoms and 2 oxygen atoms. A mole of water molecules contains 2 moles of hydrogen atoms and 1 mole of oxygen atoms. Sulfuric acid has the chemical formula H2SO4.

What is the difference between dihydrogen monoxide (H20) and hydrogen hydroxide (HOH)? ... Hydrogen hydroxide is a valid, but rather uncommon, name that emphasizes that the molecule contains a hydroxyl group. Otherwise, they are just two of the ways of naming the water molecule.

The formula H2O indicates that each molecule of this substance contains one oxygen and two hydrogen atoms. Therefore, if we ask how much hydrogen is required to make a given quantity of water, the answer is two hydrogen atoms for each oxygen atom or two hydrogen atoms per molecule.
824748
Therefore 2 mole H2O will have 2.4088×10^24 hydrogen atoms. Since one mole is defined as 6.022 x 10^23, and there are two hydrogen per molecule, that would mean that there are exactly 12.044 x 10^23 molecules of hydrogen in one mole of water.

One MOLE of hydrogen atoms contains the same number of atoms as the number of hydrogen molecules in one MOLE of hydrogen molecules, i.e., Avagadros number. However, one mole of hydrogen atoms has a mass of 1 gram while one MOLE of hydrogen molecules has a mass of 2 grams.

H2 is covalent . Hydrogen atom has only one electron. The two hydrogen atoms contribute one electron each to form a single bond which binds them to form a stable electronic configuration.
