Experiments suggest that organic molecules could have been synthesized in the atmosphere of early Earth and rained down into the oceans. RNA and DNA molecules — the genetic material for all life — are just long chains of simple nucleotides. Replicating molecules evolved and began to undergo natural selection.

In a common laboratory experiment in general chemistry students are asked to determine:_____.
Alex787 [66]
<h3>The <u>complete question</u> would be:</h3>

In a common laboratory experiment in general chemistry, students are asked to determine the relative amounts of benzoic acid and charcoal in a solid mixture. Benzoic acid is relatively soluble in hot water, but charcoal is not. Devise a method for separating the two components in the mixture.

<h3>The <u>solution</u> for that would be:</h3>

First you put the mixture in hot water and allow the benzoic acid to separate. Next funnel it and then see what's on the funnel paper. Lastly, heat the leftover water and see what's left after it evaporates.

<h3><u>What are laboratory experiments ?</u></h3>
  • Using controlled surroundings to test theories, researchers may develop laboratory experiments.
  • Laboratories are rooms or specially constructed facilities within buildings that are often found on college and university campuses and are utilized for academic research.
  • It's crucial to differentiate between experiments and other kinds of research investigations carried out in lab settings.
  • Even if a research study takes place in a lab, it is not always an experiment.
  • In order to evaluate causal conclusions regarding the links between independent and dependent variables, laboratory studies, like all genuine experimental designs, use procedures of random assignment of participants and control groups.
