Consider the following intermediate chemical equations.
pe(s)+6012(g) →
4pci,(g) → p4(s)+10c12(0)
ah, --2,439 kj
ah2 = 3,438 kj
what is the enthalpy of the overall chemical reaction pcl.(g) → pci; (g) + cl2(g)?
-999 kj
-250. kj
250. kj
999 kj

answer

the ions in solute supperate from eachouthere

the answer is c i believe

so what is the problem with your lab report and whats the subject of the lab report? i will you

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
