Covalent compounds do not conduct electric current in a water solution well because they do not dissociate into ions.

Explanation:

A covalent compound is defined as a compound formed due to sharing of electrons between the combining atoms.

As we know that like dissolves like. So, when a covalent compound is added to water then it will not dissociate into ions. Hence, it will not dissolve due to which it will not conduct electricity.

Since, we know that electricity is the flow of ions or electrons.

Thus, we can conclude that covalent compounds do not conduct electric current in a water solution well because they do not dissociate into ions.

Answer:

5Fe⁺² + MnO₄⁻ + 8H⁺ => 5Fe⁺³ + Mn⁺² + 4H₂O

Explanation:

Fe⁺² + MnO₄⁻ +  H⁺ => Mn⁺² + Fe⁺³ +  H₂O

5(Fe⁺² => Fe⁺³ + 1e⁻)      =>                        5Fe⁺² => 5Fe⁺³ + 5e⁻

<u>MnO₄⁻ + 5e⁻ => Mn⁺²    =>   MnO₄⁻ + 8H⁺ + 5e⁻ => Mn⁺² + 4H₂O</u>

                                      =>  5Fe⁺² + MnO₄⁻ + 8H⁺ => 5Fe⁺³ + Mn⁺² + 4H₂O

What is the thermal energy needed to completely melt 9.60 mol of ice at 0.0 C
inysia [295]
The  thermal energy  needed to  completely  melt  9.60  mole  of ice  at  0.0 C  is    57.8   Kj

        Explanation
ice  melt  to  form   water

The molar  heat of fusion  for   water  is  6.02  Kj/mol
Thermal energy =  moles  x  molar  heat  of  fussion  for water

=9.6  mol  x6.02 kj/mol =57.8  Kj

The alkali metals all react with water. which is the most reactive metal?
kifflom [539]
Alkali Metals (Group 1) elements experience an increase in the vigour of their reaction in water as they go down the group (as the atomic number increase). As such the most reactive Alkali Metal would be FRANCIUM, which is at the base of Group One.


Quite frankly, you do not want Francium to react with water- that's a huge explosion on your hand.
