Question

Leave the rocks submerged in the jars for about 90 minutes. Then use a spoon to carefully scoop the rocks from the jar labeled 0% Acid. Dry the rocks by patting, or blotting, them with a soft rag. After the rocks are dry, measure their mass and record it on the sticky note. Use this format: “Final Mass: ___.” Place the jar with the liquid on the counter and place the dried rocks next to the jar. Repeat this process for the other three jars. After you have recorded the final mass for each jar, complete this table.

Answer 1

The question covers Chemistry experiments intended for High School students, focusing on the study of heat capacity and chemical reaction principles such as conservation of mass.

Step-by-step explanation:

The subject of this question is Chemistry and it is suitable for High School students. The question describes various procedures that are typical for chemistry experiments, such as measuring the mass of substances before and after reactions, observing temperature changes in substances, and recording observations. These procedures aim to explore concepts such as heat capacity, chemical reactions, and conservation of mass. For example, to study heat capacity, comparing the temperature change of land (sand or soil) and water after heating helps determine which heats up faster. This touches on the real-world phenomenon of land and sea breezes. During a chemical reaction, observing mass changes before and after the reaction and writing balanced chemical equations are fundamental practices in chemistry to demonstrate the law of conservation of mass.
