Hurry will give liquid 1 reacts with liquid 2, producing a solid and a gas. using this scenario, which supports the law of conservation of mass? a) mass of liquid 1 + mass of solid = mass of liquid 2 + mass of gas b) mass of liquid 1 – mass of solid = mass of liquid 2 – mass of gas c) mass of liquid 1 – mass of liquid 2 = mass of solid + mass of gas d) mass of liquid 1 + mass of liquid 2 = mass of solid + mass of gas

Lab reagent, hypothesis test.a reference solution used as a lab reagent is purported to have a concentration of 5 mg/dl. six samples are taken from this solution and the following concentrations are recorded: (5.32, 4.88, 5.10, 4.73, 5.15, 4.75) mg/dl.these six measurements are assumed to be an srs of all possible measurements from solution.they are also assumed to have a standard deviation of 0.2, a normal distributin, and a mean concentration equal to the true concentration of the solution.carry out a significance test to determine whether these six measurements provide reliable evidence that the true concentration of the solution is actually not 5 mg/dl.
