Answer:
The standard cell potential of the reaction is 0.78 Volts.
Explanation:
Reduction at cathode :
Reduction potential of 
to Cu=
Oxidation at anode:
Reduction potential of 
to Fe=
To calculate the 
of the reaction, we use the equation:
Putting values in above equation, we get:
The standard cell potential of the reaction is 0.78 Volts.
= 9.1 × 10^6
(scientific notation)
= 9.1e6
(scientific e notation)
= 9.1 × 10^6
(engineering notation)
(million; prefix mega- (M))
= 9100000

Answer:
Molecules are made of two or more atoms
Molecules range in size
Molecules are made of atoms of the same element or different elements.
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.
