Draw the neutral major organic product when pentanoic anhydride & 2 equivalents of dimethyl amine [HN(CH3)2] react given that one equivalent of amine acts as the nucleophile and the other equivalent of amine acts as a base (relevant data: ammonium ion has a pKa ~ 10 and the carboxylic acid has a pKa ~ 5.)Input the SMILES string generated via the JSME editor.

Abullet found at a crime scene may be used as evidence in a trial if the percentage of metals match to the composition of metals in a bullet from the suspect's ammunition. a forensic scientist's analysis of the bullet shows that it contains 11.9 g of lead, 0.5 g of tin, and 0.8 b of antimony. what is the percentage of lead metal in the bullet? express your answers to the one's place.

The element that has the greatest electronegativity is

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.
