C) because the moon rotates once on its axis in the same time that it takes to revolve around the earth
Explanation: -
The moon rotates about it's axis one full time at about the same time as it takes to rotate around the earth.
This leads to only one side of the moon always appearing to Earth, called the near side.
One side of the moon is always not seen from the earth. It is called the far side of the moon.
Thus we can never see the far side of the moon because the moon rotates once on its axis in the same time that it takes to revolve around the earth

Answer: Thus 234 kJ of energy are required to produce 1.00 kilogram of iron metal
Explanation:
To calculate the number of moles , we use the equation:
Putting values , we get:
(1.00kg=1000g)
The balanced chemical reaction is:
Given :
Energy released when 2 moles of 
is produced = 26.3 kJ
Thus Energy released when 17.8 moles of is produced =
= 
Thus 234 kJ of energy are required to produce 1.00 kilogram of iron metal
