For questions #14 – 17, write an equation for the reaction of magnesium chloride and sodium oxide to produce magnesium oxide with sodium chloride. 14. show the formulas of the reactants. 15. show the formulas of the products. 16. write the balanced the equation for this reaction. 17. what type of chemical reaction is this? how do you know? 18. when is an atom unlikely to react and form chemical bonds?

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.
