You set up an experiment on a mass scale. You place a piece of metal in a salt solution, then the chemical reaction you observe starts bubbling
violently. The scale reads a loss of mass afterwards - explain whether or not
the law of conservation of mass is violated. *

Two metal blocks that have slightly different temperatures are placed next to one another. after five minutes, they both have lower but equal temperatures. according to the law of conservation of energy, what  most likelyhappened? energy was created inside the blocks.energy was destroyed inside the blocks.energy was absorbed into the blocks from outside the system.energy was transferred from the warmer block to the cooler block.
