Answer:
A
Explanation:
The purpose of the periodic table was to organize elements as they were discovered into periods and groups, according to their properties. It was not just a naming of elements, as a list.
Carbon dioxide has a total of 16 valence electrons. 1. To determine the number of valence electrons of carbon dioxide (CO2), first determine the number of valence electrons of each of the elements in the molecule.
a. We have 1 carbon (C) molecule, and 2 oxygen (O) molecules.
b. The carbon molecule has 4 valence electrons and each oxygen molecule has 6 oxygen molecules.
2. Add up the valence electrons of each of the elements
4 + (2 x 6) = 16
(from C) (2 oxygen molecules, with 6 valence electrons each)
Thus, CO2 has a total of 16 valence electrons.
The number of valence electrons can be more clearly seen from the Lewis structure of the CO2 in the figure below (Source: http://chemistry.tutorvista.com/inorganic-chemistry/bonding-electrons.html). The the dots surrounding the letters represent the valence electrons.

Answer:
Explanation:
crystallization The crystallization temperature of a brine is the temperature at which a solid phase begins to form, resulting in a mixture of solid particles and solution. These solids may be salt crystals or water crystals (ice). It is the point at which the minimumcrystallization temperature can be realized
The metric prefixes which is not one multiple of ten when moving forward or backward between prefixes is: none of the above
Option c is the correct answer
<h3>What is metric prefix?</h3>
A metric prefix simply refers to a unit prefix that precedes a basic unit of measure to indicate a multiple or sub-multiple of the unit.
So therefore, the metric prefixes which is not one multiple of ten when moving forward or backward between prefixes is: none of the above
Complete question:
Which of the following metric prefixes are not one multiple of ten when moving forward or backward between prefixes?
a. micro
b.nano
c. none of the above
