Select the correct answer from each drop-down menu. Justus has a flexible container that holds 200 milliliters of air at a temperature of 300 kelvins and a pressure of 100 kilopascals. Justus wants to decrease the volume of the air inside the container to 100 milliliters. He can do this either by changing the temperature to kelvins or by changing the pressure to kilopascals.

Draw the structure for 5-isopropyl-2-methyl-3-nonene

The content of manganese (mn) in steel was determined spectrophotometrically and with the use of the standard addition method. an unknown sample of mn from a digested steel sample gave an absorbance of 0.185 when analyzed spectrophotometrically. when 5.00 ml of solution containing 95.5 ppm mn was added to 50.0 ml of the unknown steel solution (digested sample), the absorbance was 0.248. calculate the concentration, in parts-per-million (ppm), of mn in the digested steel sample solution.
