Ms. block's students are studying chemical reactions. a classic reaction occurs when a metal is added to hydrochloric acid. miguel and kai added 30g of hydrochloric acid (hcl) to 30g of magnesium (mg) in a large test tube; bubbles appeared, the test tube felt warm, and they could no longer see the magnesium. they found that the mass of the products of the reaction was 52g. since the law of conservation of matter stated that matter cannot be created or destroyed, they was puzzled about the difference in mass. what is the best explanation for the missing 8g?
