hy was it important to perform several tests on the unknown solid? Opifferent tests allow you to collect more material for weighing on the balance for proper identification. Some solids have similar properties, so performing several tests allows you to distinguish among the different solids. Performing several tests is more scientific. One test would have been enough, but the lab manual required several tests to be performed.
