Answer:
A binary covalent compound is composed of two different elements (usually nonmetals). For example, a molecule of chlorine trifluoride, ClF3 contains 1 atom of chlorine and 3 atoms of fluorine.
Rule 1. The element with the lower group number is written first in the name; the element with the higher group number is written second in the name. Exception: when the compound contains oxygen and a halogen, the name of the halogen is the first word in the name.
Rule 2. If both elements are in the same group, the element with the higher period number is written first in the name.
Rule 3. The second element in the name is named as if it were an anion, i.e., by adding the suffix -ide to the root of the element name (e.g., fluorine = F, "fluoride" = F-; sulfur = S, "sulfide" = S2-).
Rule 4. Greek prefixes are used to indicate the number of atoms of each element in the chemical formula for the compound. Exception: if the compound contains one atom of the element that is written first in the name, the prefix "mono-" is not used.
Explanation:
Given the following choices, determine which best suits as a characteristic of a hurricane.
Answer Choices:
A. Hurricanes occur mostly inland
B. Hurricanes create widespread damage
C. Hurricanes can only last for a short amount of time
D. Hurricanes gain strength after passing overland
Best Answer: B. Hurricanes can create widespread damage.
Reason: A would not be correct since it is more of a variable, due to the fact that hurricanes usually begin near the coastlines, hurricanes are in fact capable of moving inland for atleast 100 miles before it dies down to a tropical storm or depression.
C is not correct since hurricanes can last up to a whole week which is approximately 168 hours.
D is not correct since it is another variable in which hurricanes can decrease in strength if it comes into contact with cool and dry air which is the opposite of warm and moist which it needs in order to occur.
Therefore, the best choice is B. Hurricanes can create widespread damage, hurricanes can unleash a staggering arsenal of mother nature's strength and the most damage a hurricane has caused can go up to 125 billion USD in damages.
Molarity is a measure of a solution's concentration calculation by getting the ratio of the number of moles of solute to the total volume of solution. This has a unit of M or molar, equivalent to mole/L.
It is more important and meaningful to know the molarity rather than if the solution is dilute or concentrated because molarity gives the QUANTITATIVE approach of knowing the concentration while the second one only gives us the QUALITATIVE description of the solution. Hence, we are able to calculate for other unknown parameters if we have the molarity known.
