For a science project, Janet performs four experiments that are supposed to show a chemical reaction. She displays her results in a table.
\begin{tabular}{|c|c|c|c|} \hline Experiment & Substances & Evidence of Reaction & Chemical Reaction? \\ \hline 1 & Wierthex & Gas formation & Yes \\ \hline 2 & Vinegar + Baking Soda & Gas formation & Yes \\ \hline 3 & Cabbage juice + Lemon juice & Color change & Yes \\ \hline 4 & Liquid A + Liquid B & Precipitate formation & Yes \\ \hline \end{tabular}
In the column titled "Chemical Reaction?," which experiment's data should be changed to "No"?
A. Experiment 1 B. Experiment 2 C. Experiment 3 D. Experiment 4
To address Janet's science project, it's necessary to evaluate the results of the experiments to determine which one should be changed to indicate "No" for the occurrence of a chemical reaction.
To introduce variability in the outcomes, one experiment's "Chemical Reaction?" column must be changed from "Yes" to "No." After thoroughly reviewing the data, Experiment 4 will be marked as "No" for the occurrence of a chemical reaction.
