Answer is: chemical formula of blue vitriol is CuSO₄.
In this molecule copper has oxidation number +2 and sulfate has oxidation number -2, copper(II) sulfate has neutral charge (+2 +(-2) = 0).
Copper sulfate is produced industrially in chemical reaction of copper metal and hot concentrated <span>sulfuric acid.</span>

Balance each reaction and write its reaction quotient, Qc:(b) POCl₃(g) ⇄ PCl₃(g) + O₂(g)
Komok [63]

When we balance the given equation

      POCl₃(g) ⇄ PCl₃(g) + O₂(g)

We will get

      2POCl₃(g) ⇄ 2PCl₃(g) + O₂(g)

Solution:

Balancing the given equation

      POCl₃(g) ⇄ PCl₃(g) + O₂(g)

Balancing the number of O

      2POCl₃(g) ⇄ PCl₃(g) + O₂(g)

Balancing the number of P and Cl

      2POCl₃(g) ⇄ 2PCl₃(g) + O₂(g)

We get the balanced equation

      2POCl₃(g) ⇄ 2PCl₃(g) + O₂(g)

The reaction quotient will be

     Qc = [product] / [reactant]

     Qc ​= [PCl₃(g) + O₂(g)] / [POCl₃(g) ]

Hi:) why covalent substances don’t have free moving ions / electrons?
Igoryamba

Answer:

Covalent compounds don't contain ions because they make bonds by sharing electrons. In addition, they don't have any charge carries that are free to move so they can't carry electric current

Why do polar and non polar molecules have different properties?
Margaret [11]
The greater the electronegativity difference, the more ionic the bond is. Bonds that are partly ionic are called polar covalent bonds. Nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
