Answer:
B.
Explanation:
One mole is the amount of substance that contain the Avogadro number which is equal to 6.022×10^23 atom, molecules or ions.
Sodium has 11 protons, therefore number of neutrons must be 23 – 11 = 12 neutrons.
Sodium has 12 neutrons.
<h3>What are neutrons?</h3>
The neutron is a subatomic particle with the symbol n that is slightly heavier than a proton and has a neutral charge (i.e., neither a positive nor a negative charge). Atoms' nuclei are made up of protons and neutrons. Protons and neutrons are both referred to as nucleons because of how similarly they function inside the nucleus and because they both have masses that are about equal to one atomic mass unit. Nuclear physics describes their characteristics and interactions.
The arrangement of electrons around an atom's hefty nucleus largely determines its chemical characteristics. The amount of protons, or atomic number, determines the charge of the nucleus, which determines the electron configuration.

Bioaccumulation refers to the accumulation of chemicals in a living organism. The compound or chemical accumulates at a rate faster than it is being metabolized or excreted by the organism. Chemicals bioaccumulate by binding to the proteins and fats in an organism while others bioaccumulate through the repeated consumption of contaminated organisms.
Pesticides containing chemicals that dissolve easily in fat but not in water tend to bioaccumulate. Pesticides that contain chemicals that can easily be metabolized by organisms do not bioaccumulate. In summary, the nature of the chemical used in pesticides and the capability of organisms to metabolize the said chemicals can dictate whether it will bioaccumulate or not.
<span>Kinetic energy is the energy at move or at motion. The kinetic energy of objects depend on its mass (m) and its </span>velocity (v)<span>. The mass of an object can be measured in kilograms while its mass can be measured in meters per second. The objects' energy at motion is very dependent to its mass and velocity therefore, the formula in finding the kinetic energy of an object is </span>
K = 1/2 x mass (m) x velocity (m/s)2
<span>On the other hand, the kinetic energy of atoms and molecules are measured differently. It is measured through temperature.<span>
