Simple distillation is a method for separating the solvent from a solution
EXAMPLE: water can be separated from salt solution, because water has a much lower boiling point than salt. When the solution is heated, the water evaporates.
Answer is: H₂PO₄⁻ (d<span>ihydrogen phosphate).
Chemical reaction: HPO</span>₄²⁻(aq) + H⁺(aq) ⇄ H₂PO₄⁻(aq).
According to Bronsted-Lowry
theory acid are donor of protons and bases are acceptors of protons (the
hydrogen cation or H⁺). Hydrogen phosphate is Bronsted base and it can accept proton and become conjugate acid.
19.927 moles are in 1.20 times
atoms of phosphorus.
<h3>What are moles?</h3>
A mole is defined as 6.02214076 ×
of some chemical unit, be it atoms, molecules, ions, or others.
1 mole of any substance contain Avogadro's number of molecules so we can calculate the number of moles by dividing the provided number of atoms over Avogadro's number to obtain the number of moles .
Moles= 
Moles= 1.20 X
atoms ÷ 6.022 X
= 19.927
Hence, 19.927 moles are in 1.20 times
atoms of phosphorus.
