Asolution of sulfuric acid is titrated with a solution of sodium hydroxide to the phenolphthalein end point. the sample of sulfuric acid is 25.00 ml. the titration takes 32.08 ml of 0.09946 m sodium hydroxide.
a.) write out a balanced equation for the reaction.

b.) calculate the molarity of the sulfuric acid.

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.

What is the mass of phosphorous in a 51-kg person

Phosphorous can form an ion called phosphide, which has the formula p3−. this ion can form an ion called phosphide, which has the formula p3−. this ion properties very similar to those of pforms when a phosphorus atom loses three protonsis called a cationcontains 18 electrons
