Question

Four different stations have various chemicals at them. Which station will provide the opportunity for the most possible chemical changes if you use only the items listed below as well as the air around you?

Station 1 - 50 mL water, beaker, blue paint, yellow paint, red paint, bunsen burner, lighter

Station 2 - Magnesium ribbon, bunsen burner, lighter, watch glass

Station 3 - Hydrochloric acid, sodium hydroxide, litmus paper, two test tubes, magnesium ribbon

Station 4 - Hydrochloric acid, magnesium ribbon, test tube, bunsen burner, lighter, litmus paper

Answer 1

Station 4 provides the greatest opportunity for varied chemical changes, including reactions between hydrochloric acid and magnesium, acid-base neutralizations, and combustion.

Step-by-step explanation:

The student is inquiring about which station among the four provided will allow for the most possible chemical changes when mixed with the surrounding air. Considering the materials at each station, Station 4 appears to offer the greatest opportunity for chemical reactions, such as the reaction between hydrochloric acid and magnesium ribbon, which produces hydrogen gas and magnesium chloride. This station also allows for the observation of the acid-base reaction with the accompanying litmus paper test and for combustion reactions using the bunsen burner and lighter.
