By looking at it and if it is making a single movement it is moving.
Answer:
NH4Cl > Li2SO4 > CoCl3
Explanation:
Let us recall that the freezing point depression depends on the molality of the solution and the number of particles present.
Let us also recall that freezing point depression is a colligative property. It depends on the number of particles present in solution.
Usually, the more the number of particles present, the lower the freezing point. Hence, NH4Cl which has only two particles will have the highest freezing point while CoCl3 which has four particles will have the lowest freezing point.
A method of procedure that has characterized natural sciences the 17th century, consisting in systematic observation, measurement, and experiments, and the formulation, testing, and modification of hypotheses.
The last step (step 5) in the experiment is to write a conclusion for the experiment. (Option B).
<h3>What is an experiment?</h3>
The essence of an experiment is to be able to establish a cause and effect relationship. It is only when we carry out a carefully controlled experiment that we can say that x causes y because the data would support our findings.
After, we have carried out an experiment, the next step is to put the evidences together and then try to arrive at a logical conclusion for the experimental procedure.
Thus the last step (step 5) in the experiment is to write a conclusion for the experiment. (Option B).
