Astudent states that this structural formula represents a hydrocarbon. h h i i i i h h is the student correct? yes, a hydrocarbon is any compound that contains a carbon backbone. yes, a hydrocarbon is any compound that contains hydrogen and oxygen. no, a hydrocarbon contains only carbon and hydrogen atoms. no, a hydrocarbon contains at least one double or triple bond.

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.

Answer : option c) heat is released during the process.explanation :

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.

C) electrons encircling a nucleus with neutrons and protons
