Alka-seltzer is an antacid that is dissolved in water before use. for an experiment, three tablets of alka-seltzer are dissolved in three beakers, each containing 50 ml of water: beaker a's water is 10° c; beaker b's water is 50° c; and beaker c's water is 80° c. which answer correctly orders the reaction rates of the three beakers from fastest to slowest reaction? beaker a > beaker b > beaker c beaker c > beaker b > beaker a beaker b > beaker a > beaker c beaker a = beaker b = beaker c

Astudent wished to add a new experiment to chapter 2 by investigating whether the mass of water changes when it is heated. the mass of a beaker containing a sample of water at 20°c was 109.44 g. after heating the sample to 60°c, the com- bined mass of the beaker and water was 109.08 g. do these results contradict the law of conservation of mass? explain your reasoning.
