A student states that this structural formula represents a hydrocarbon.
DedPeter [7]
Answer: <span>Yes, a hydrocarbon is any compound that contains hydrogen and oxygen.

Justification:

First, I will try to rewrite the given structural formula since it is misrepresented.

This should be the right structural formula:

       H    H
       |      |
H - C  -  C - OH
       |      |
      H     H

And, yes the definition of hydrocarbon is that it is most simple organic compound constitured only by atoms of carbon (C) and hydrogen (H).

By the way, that hydrocarbon is also represented as CH3 - CH2 OH, it is an alcohol (since it has the functional group OH) and its name is ethanol.

A meteorologist wants to create a visual aid different gases in earths atmosphere which type of chart or graph would best convey
Karolina [17]

Answer:

A pie chart

Explanation:

A pie chart would be the ideal type of chart to create this visual aid. A pie chart is simpler visually and easily understood. It can show data as portions or percentages of a whole. Since what they want is to present the different gases found in Earth's atmosphere, they can show what percentage of the different gases make up the atmosphere.

It is simpler because the size of each portion or "slice" of the pie chart itself can reveal a lot about the data without even reading the numbers.
