Moles of ammonium sulfide = 5.80 mol
The formula of ammonium sulfide is (NH₄)₂S
So each molecule of ammonium sulfide has (4 x 2) or 8 atoms of H
One mole of ammonium sulfide has 8 moles of H
5.80 mol of ammonium sulfide has (8 x 5.8) or 46.4 moles of H
As per the definition of Avogadro's number, 1 mole = 6.022 x 10²³ atoms
46.4 moles of H x (6.022 x 10²³ atoms/ 1 mole of H)
= 2.8 x 10²⁵ H atoms
Therefore, 2.8 x 10²⁵ H atoms are in 5.80 mol of ammonium sulfide.
C liquids with different boiling points, to distill you only use one liquid
Answer:
If hydrochloric acid is a polar covalent compound, explain why in aqueous solution it conducts current similarly to an ionic compound.
This occurs because the current is transmitted by the charges of its atoms.
Explanation:
Hydrochloric acid is a compound that is made up of atoms with partial charges, which means that it is a polar molecule. H atoms have a positive partial charge, while Cl atoms have a negative charge, making the molecule as a whole have a neutral charge.
Being a dipole compound, water can dissolve molecules of this type, separate anions and cations. When atoms are separated from these molecules they release ions. In the case of HCl, being an acid, H+ and Cl- ions are released. This separation of charges causes electric current to be conducted.
