Convert grams to moles [grams/molar mass] ~ Moles
Convert moles to atoms [moles * 6.02 x 10^23] = Atoms
Half of 6.02 x 10^23 is 3.01 x 10^23 so here is our answer.

Answer:

D. pUC-chloramphenicol(minus)

Explanation:

It contains chloramphenicol resistance gen, the PMB1 posses origin of replication (ori), beta-galactosidase coding gen Laz. It also has pUC18 with many cloning site in the Lac Z gene which makes the recombinant clones to be verified via culture plates which is made up of IPTG and X- Gal.

SEP Develop a Model: The element argon (Ar) has eight valence electrons and is a liquid at very low temperatures. Sketch a model

Flura [38]

Larger molecules experience larger dispersion forces due to more distance of valance of electrons from the nucleus.

<h2>Cause of stronger dispersion force
</h2>

Larger atoms and molecules have stronger dispersion forces than smaller atoms and molecules because in a larger atom or molecule, the valence electrons are present farther from the nuclei than in a smaller molecule.

They are less tightly held to the nuclear charge present in the nucleus and can easily form temporary dipoles so we can conclude that larger molecules experience larger dispersion forces due to more distance of valance of electrons from the nucleus.
