Answer:

High

Explanation:

When the unknown compound contains an impurity that is insoluble in cyclohexane, the solute will not dissolve in the solvent (cyclohexane) completely. ∆T of the solution would be smaller than it is supposed to be, when compared to a compound without such insoluble impurity. Molecular weight determination won't be accurate because the molecular weight obtained will be higher as a result of the fact that the mass of the solute would include the actual solute that is changing the temperature and the excess mass of the impurity.

The order would be coefficient, law of conservation of mass, products, and reactants respectively.

<h3>Word matching</h3>

The number written in front of a chemical symbol in an equation is called a coefficient.

The total mass of a system being unchanged is known as the law of conservation of mass

The substances made in chemical reactions are called products.

The starting materials in chemical reactions are called reactants.
