If someone did this experiment correctly and collected less than 100% of the sample, which component is most likely lost based on our procedure and why? Human error is not an acceptable answer.

Suppose your instructor places a can of regular and diet cola in a large container filled with water. What might you expect happen based on the results of this experiment?

Read the descriptions below of two substances and an experiment on each. Decide whether the result of the experiment tells you the substance is a pure substance or a mixture, if you can. • Sample A is 100. mL of a clear liquid. The liquid is heated in a flask until it boils. The vapor that rises off the boiling liquid is collected for 10 minutes and cooled until it condenses into a separate beaker. The density of the liquid that remains in the flask is then measured, and turns out to be 1.04 g/mL. The density of the liquid that boiled off turns out to be 0.77 g/mL. Sample B is a solid yellow cube with a total mass of 50.0 g. The cube is divided into two smaller 25.0 g subsamples, and the volume of each subsample is measured. The volume of the first is 48.2 cm³ and the volume of the second is 58.1 cm³. When the experiment is repeated with a new 50.0 g. sample, the volume of the two 25.0 g subsamples is 52.2 cm³ and 50.8 cm³.

The Scientific Method Group of answer choices isn't used much in modern chemistry. is a strict set of rules and procedures that lead to inarguable fact is based on continued observation and experiment is just a theory
