(2S,3R)-2-Bromo-3-phenylbutane undergoes an E2 elimination when treated with sodium ethoxide. Draw all possible Newman projections for the bond relevant for the elimination reaction, and use those Newman projections to explain the stereochemical outcome of the reaction. Draw the final product and provide its IUPAC name.

Yes i think so not 100 percent sure though

Compound with sulfer  is bright red 

Those are different gas lawshere is a brief description of themcharles's law states that volume and temperature are directly proportional to each other as long as pressure is held constant.  boyle's law asserts that pressure and volume are inversely proportional to each other at fixed temperature.gay-lussac's law introduces a direct proportionality between temperature and pressure as long as it is at a constant volume.    source:
