It is either a proton or a neutron
Covalent Bonds are formed by mutual sharing of electrons
The amount of water that could we get if you started with 250.0 grams of hydrogen is 2,250 grams.
<h3>What is moles - mass realation?</h3>
Moles (n) and mass of any substance are related to each other according to the given equation as:
n = W/M, where
W = given mass
M = molar mass
Given balanced chemical reaction is:
2H₂ + O₂ → 2H₂O
Moles of 250g of H₂ = 250g / 2g/mol = 125mol
From the stoichiometry of the reaction it is clear that,
2 moles of H₂ = produces 2 moles of H₂O
125 moles of H₂ = produces 125 moles of H₂O
Now mass of water will be calculated as:
Mass = (125mol)(18g/mol) = 2,250g
Hence required mass of water is 2,250 grams.

Answer:Each bulb will be as bright as the first bulb was
Explanation:
Atomic number=number of protons (and electrons, but that doesn't matter in this answer)
Atomic mass=number of protons+number of neutrons
Atomic mass=atomic number+number of neutrons
Atomic mass-atomic number=number of neutrons
88-38=number of neutrons
number of neutrons=50
