Answer:

3 (three).

Explanation:

Hello,

Perhaps, you are talking about the following undergoing chemical reaction:

CaSO_4+AlCl_3-->CaCl_2+Al_2(SO_4)_3

Thus, balancing it by inspection, one obtains:

3CaSO_4+2AlCl_3-->3CaCl_2+Al_2(SO_4)_3

In such a way, a 3 (three) must be placed in front of the calcium chloride CaCl_2 in order to balance calcium and consequently the rest of the chemical reaction.

Best regards.

3 to balance the calciums on both sides of the equation, but only if that balances the Cl on both sides of the equation to because you now have 6 Cl and 3Ca

What energy is required to remove the remaining electron from singly ionized helium?
skelet666 [1.2K]

To remove one electron from singly ionized helium, will require approximately 54.4 eV or 8.72 1020 J of energy.

The amount of energy required by an isolated, gaseous molecule in the electronic state of the ground to absorb in order to discharge an electron and produce a cation has been known as the ionization energy. The amount of energy required for every atom in a mole to drop one electron is most often given as kJ/mol.

Anything that causes electrically neutral atoms and molecules to gain or lose electrons in order to become electrically charged atoms as well as molecules .

Therefore, the "To remove one electron from singly ionized helium, will require approximately 54.4 eV or 8.72 1020 J of energy."
