no, refer to the law conservation of mass: in a chemical reaction, energy can niether be created nor destroyed.
Answer:
- Hydrogen can be changed to helium in fusion processes with an associate release of energy. This effectively destroys or removes the hydrogen and converts it to something else.
- Hydrogen atoms can also be converted to energy (destroyed) through contact with anti matter particles.
- As far as hydrogen creation this was an event occurring shortly after the Big bang. Elementary particles (quarks) begin to bond in trios, forming photons, positrons and netrinos and their antiparticles. After about one hundredth of a second hydrogen started to form.
- Hydrogen can also be created when the atoms of fissionable materials split

What is the product of H2?
The product of H2 is hydrogen gas (H2) composed of diatomic molecules.
How many molecules (not moles) of NH3 are produced from 1.57104 g of H2?
The answer is 1,57.10e27 molecules.
What molecules is the heaviest CO2 H2O co or h2?
CO2
How many molecules are in 7.3 L of H2 at STP?
At STP, 1 mole of any gas occupies 22.4 L. So, 7.3 L of H2 corresponds to 7.3/22.4 = 0.3263 mol. Since 1 mol of H2 contains 6.022 x 10^23 molecules, the number of molecules in 7.3 L of H2 at STP would be 0.3263 mol x 6.022 x 10^23 molecules/mol = 1.963 x 10^23 molecules.
What type of chemical bond occurs between atoms in molecules such as h2 ch4 nh3 h2 cch2 n2 cl2 and many large biological molecules?
covalent bonds --- sharing electrons
How many hudrogen molecule are there in 10grams of hydrogen?
There are approximately 1340 molecules of hydrogen in 10 grams of hydrogen.
How many moles of hydrogen gas contained in 9.03x1023?
Given/Known:1mole of H2 = 2.01588g H21mole of H2 = 6.022 x 1023 molecules H21) Convert molecules of H2 to moles of H2 by doing the following calculation.9.4 x 1025 molecules H2 x (1mol H2/6.022 x 1023 molecules H2) = 156mol H22) Convert the moles of H2 to mass in grams of H2.156mol H2 x (2.01588g H2/1mol H2) = 314g H2
What is the product of H2?
The product of H2 is hydrogen gas (H2) composed of diatomic molecules.
In the equation 2 H2 plus O2 the H2 molecules are?
In the equation 2 H2 + O2, the H2 molecules are reactants that will participate in the reaction. They will combine with the O2 molecules to form water (H2O) molecules in the chemical reaction.
calculate the number of moles in H2 molecules in 4g H2?
2 moles.
How many molecules of H2 are required to completely react with six molecules of N2?
Three molecules of H2 are required to completely react with six molecules of N2 to form ammonia (NH3) according to the balanced chemical equation: N2 + 3H2 → 2NH3.
What do you mean by 3 H2?
It might refer to 3 molecules of H2 (diatomic hydrogen).
How many molecules of H2 are present in 0.175 moles of H2?
There are 1.05 x 10^23 molecules of H2 present in 0.175 moles of H2. This is determined by Avogadro's number, which states there are 6.022 x 10^23 molecules in 1 mole of a substance.
How many molecules of H2(g) are there in a 21.25 gram sample?
To calculate the number of molecules, you first need to determine the number of moles of H2 in the 21.25 gram sample using the molar mass of H2 (2 grams/mol). Then, use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules.
How many molecules (not moles) of NH3 are produced from 1.57104 g of H2?
The answer is 1,57.10e27 molecules.
What are two molecules of hydrogen represented by?
Two molecules of hydrogen arte represented by '2H2'. This means H2 & H2 . 'H2' is ONE molecule of hydrogen . It consists of two(2) atoms of hydrogen . It can be represented by 'H-H'. NB With the exception of the Noble Gases , all other gas molecules contain at least two atoms.
Why does H2 molecules exist when He2 does not?
H2 molecules exist because hydrogen has the ability to form stable covalent bonds by sharing electrons, which allows it to form molecules like H2. In contrast, helium is an inert gas with a full outer electron shell, making it highly stable and less likely to form bonds with other helium atoms to create He2 molecules.
