Answer:
Metal is a conductor. it takes in heat very well. wood is an insulator. it takes in heat too, but less of it. this makes the wood handle cooler and the metal handle hot
The error caused will lower the number of moles when he did not do the second heating.This question is related to the empirical formula.
<h3>What is Empirical formula ?</h3>
A formula giving the proportions of the elements present in a compound but not the actual numbers or arrangement of atoms.
The empirical formula is the simplest ratio of atoms in a given compound.
we know that heating is used to eliminate most of the water molecules which are attached to the compound in the question, it's given that the second heating was not performed by the students.
This means that there are still some water molecules attached to the compound. This will imply that higher mass will be calculated for the compound because the water molecules are also considered.
So now, if we look at the calculation for the number of moles of water in this, we can say that this will be lower than the actual amount.
This is because there are some unaccounted moles of water which are still attached to the compound and these will be accounted in the compound mass rather than the waters. Therefore, the number of moles will be lower.
Hence, The error caused will lower the number of moles when he did not do the second heating.

The correct answer is : Circulatory and respiratory.
This condition primarily affects Caroline's circulatory system. Since the main purpose of the circulatory system is to supply the rest of the body with oxygen, this condition is greatly reducing the effectiveness of the circulatory system.
The decrease in oxygen supply to the lungs causes the reduction of the respiratory system effectivness as well, since the lung cells need oxygen for their metabolic processes.
