If two carbon atoms are bonded by a double covalent bond, how many additional bonds can each carbon atom form?
Umnica [9.8K]

Answer:

2

Carbon Is tetravalent. This means that at any particular point in time, the number of bonds carbon can form at a particular time is 4. Now in this particular question, there is already a double bond between the two carbon atoms. This means that each of the carbon atom has the chance to fulfill it tetra valency by attaching just two bonds to itself.

Hence, to complete the property of its tetra valency, two more bonds needed to be added to the two carbon atoms

Determine the formula unit for the compound formed when each pairs of ions interact.
maksim [4K]

The formula unit of compounds formed depends on the valency of the combining ions.

The formula unit is the smallest unit of an ionic substance that gives us a picture of the ratio in which ions are combined in the ionic compound.

Usually, the formula unit is written based on the valency of the ions.

For the ions listed;

Li+ and 02- forms Li2O

Mg2+ and S2- forms MgS

A13+ and CI- forms AlCl3

Na+ and N3- forms Na3N
