After centrifugation of the sample, the student was not careful and some of the solid was transferred to the Erlenmeyer flask al
Tju [1.3M]

The fact that some of the solid was transferred would decrease the mass of the limiting reactant.

<h3>What is the limiting reactant?</h3>

We know that in a chemical reaction, there are at least two substances that are combined in order to give the product of the reaction. We also know that the product that we obtain must be in accordance to the stoichiometry of the reaction.

It is common to see that one of the reactants would be present in a very large amount while the other reactant would be present only in quite a small amount. The reactant that is present in a small amount is said to be the limiting reactant while the one that is present in the large amount is said to be the reactant that is in excess.

Having said this, we know that the mass of the limiting reactant can be obtained from the mass of the solid that is obtained after the reaction.

If we do not take out all of the solid from the centrifuge, the mass would not be accurately weighed and the mass of the limiting reactant would not be accurately determined.

kupik [55]
D) Physical Change, I would argue, because you can reverse this change by boiling off (evaporating) the water. But there are arguments for both physical and chemical change being what occurs.

A physical change results in a change of the material's appearance, but no new chemical products result. A chemical change involves a chemical reaction, with new substances produced as a result of the change.
