Answer: Polar molecules have an equal number of positive and negative particles.

Explanation: There are two types of molecules:

1) Polar molecules: This molecule is formed when two different atoms having different electronegativities combine together. The more electronegative atom attracts the shared pair of electron towards itself, thus acquiring a partial negative charge and other atom acquiring partial positive charge. This results in the formation of dipole. In this equal number of positive and negative particles.

For example: HCl. As this molecule is covalent in nature and is also a polar molecule.

2) Non-polar molecules: This is formed when two atoms of same electronegativity combine together. For Example: $H_2,O_2$ etc.

Hence, Polar molecules have an equal number of positive and negative particles.

Answer:

The pellet fraction will be most radioactive because the heavy protein part of ghost will be present in the the pellet fraction.

Explanation:

supernatant can be defined as a liquid part that lies above the sediment of the centrifuge tube on the other hand pallet is a solid material present at the bottom end of the centrifuge tube.

As protein molecules in the given experiment is radio labelled that"s why the pellet fraction will be radio labeling part because the heavy protein molecules will be present in the pellet fraction.

Answer:

D. It will decrease by a factor of 4

Explanation:

According to the question , the equation follows :

$A+B\rightarrow C+D$

Rate law : This states the rate of reaction is directly proportional to concentration of reactants with each reactant raised to some power which may or may not be equal to the stoichiometeric coefficient.

$Rate\ \alpha [A]^{a}[B]^{b}$
