Determine if each of the following statements about chiral molecules is True or False and select the best answer from the dropdown menus. All R stereocenters are dextrorotatory. Chiral centers in organic molecules will have 4 different groups attached to a carbon. A racemic mixture has an optical activity of 0. Normal linear amines can be chiral centers. Compound C has an optical activity of 0. If the R isomer of a molecule has an optical rotation of 25.7o then the S isomer of the molecule will have an optical rotation of -25.7o. A CN is higher priority than a CH2OH. All molecules with c

the solar system used to have much dust particles option no d

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
