The number of molecules of hydrogen will be required to produce 1.60 mol of water are 9.6×10²³.
<h3>What is the stoichiometry?</h3>
Stoichiometry of the reaction gives idea about the relative amount of moles of reactants and products present in the given chemical reaction.
Given chemical reaction is:
2H₂ + O₂ → 2H₂O
From the stoichiometry of the reaction,
2 moles of hydrogen = produces 2 mole of water
1.6 moles of hydrogen = produces 1.6 mole of water
As we know that in 1 mole of any substance 6.022×10²³ entities of that substance are present.
In 1.6 mole of H₂ gas = (1.6)(6.022×10²³) = 9.6×10²³ molecules of hydrogens are present.
Hence 9.6×10²³ molecules of hydrogens are present.

Answer - the degree of compactness of a substance.
Answer: 2) Electron X absorbs energy when it changes to a higher energy level.
Explanation:
The electrons in an atom exist in various energy levels. When an electron moves from a lower energy level to a higher energy level, energy is absorbed by the atom. When an electron moves from a higher to a lower energy level, energy is released (often as light).
