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.

Answer:it conduct thermal conductivity because of the heat it holds
Explanation:
Ionic substances produce ions in solution while molecular substances produce molecules in solution.
<h3>What is a solution?</h3>
A solution is a combination of solute and solvent. The species that occur in solution depends on the type of substance that was dissolved. Since the table is not shown, we do not know exactly what compounds were dissolved in solution.
Generally, if an ionic substance is dissolved in solutions that ions are present in the solution. If a molecular substance is dissolved in solution, molecules are present in solution.
