PLEASE HELPP!!! WILL REWARD BRAINLIEST AND TONS OF POINTS Please help me with the calculations. I am very confused.

The data (In order)
1. 100 ml
2. 0.10 M
3. 0.62 g
4. 0.77 g
5. 160 mg
6. 360 ml

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

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: )
