What has to happen in order for work to be done

Explanation:

For work to be done, force must be applied to move an object in the direction of the applied force.

Work is the product of force and distance. Workdone describes a change of energy between places.

If we apply force to a body without moving it through a distance, no work is done.

Work is only done when force is applied to move or displace a body.

If we only apply force and no movement occurs, no work is done..

The unit of force is Joules.

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!

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
