Nathaniel Wyeth, developer of the plastic soft drink bottles, dreamed of the day when we will be able to melt down plastic bottles, reinforce the fibers and make car bodies. Then when we are done with the cars, melt down the car bodies and make bottles out of them. This would be an ultimate example of.

A. biodegradation.
B. incineration.

D. reuse.

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.
