What is the best reason for a student to remove a dangling bracelet when heating test tubes of acidic solutions in a hot water bath in a chemistry lab? to avoid reactions of the metal with gases in the lab to reduce the risk of bums from heat conducted through the metal to minimize the chance the bracelet pulling over a test tube, causing a spill to prevent misreading the temperature of the bath on a thermometer
