Determine the number of bonding electrons and the number of nonbonding electrons in the structure of bef2. enter the number of bonding electrons followed by the number of nonbonding electrons, separated by a comma, in the dot structure of this molecule (e. g., 1,2).

4,12.

Explanation:

Hello,

The considered molecule, beryllium fluoride, , has the Lewis structure shown on attached picture wherein one sees that there are four bonding electrons (two pairs of electrons) and twelve nonbonding electrons (six per fluorine).

Best regards.

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.

i wish i could but this one is weird give me abc and i can solve it.
