Write out the balanced equation for the reaction that occurs when ca and nacl react together. you do not need to make your subscripts smaller; just write them out as regular numbers. for example: h2o.

Use the table to identify the phase and phase changes of the elements under the given conditions. write the name of the substance, phase, or phase change

Explain what happens at the saturation point when adding salt to water at room temperature.

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.
