Which of the following is the correct equation for calculating work? work = force × distance work = force × acceleration work = force × energy work = force × weight
@llmones

Option (a) is the correct answer.

Explanation:

Work is defined as the amount of energy or force required to move an object from its initial position.

For example, a person applies 10 N of force in order to move a wooden box from point A to point B.

This means that the man has done some work in order to move the wooden box.

Mathematically,       Work = Force × Distance

Thus, we can conclude that out of the given options, work = force × distance is the correct equation for calculating work.

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: )

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
