What has a complete ionic equation of Mg(s) + Zn2+ + 2NO3 → Mg2+ + 2NO3 + Zn(s)? O A. Mg(s) + Zn2+ → Mg2+ + Zn(s)
O B. Mg(s) + Zn(NO3)2(aq) + Mg(NO3)2(aq) + Zn(s)
O C. Mg(NO3)2 + Zn(s) → Zn2+ + 2NO3 + Mg(s) O D. Mg(s) + 2Zn(NO3)(aq) + 2MgNO3(aq) + Zn(s)​

Margaret wants to make an orange flavored drink by stirring powdered drink mix into a glass of water. she doesn't like drinks that have small clumps of powdered solid in them, so she wants the drink to be a perfect solution. what factors should margaret not consider when deciding how much powder to add to her glass of water?

Joe shines white light into a bowl half full of water at an angle of incident of 27.5°. calculate the angle of refraction in the water given the indices of refraction for air and water are 1.00 and 1.36, respectively.

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.
