Ibuprofen, a well-known non-steroidal anti-inflammatory drug, has chirality. only the s enantiomer has anti-inflammatory activity (although the r enantiomer is converted slowly by the body into the s enantiomer). add wedge-and-dash bonds to complete the perspective structures of the two stereoisomers of ibuprofen.

Nitric oxide (no) can be formed from nitrogen, hydrogen and oxygen in two steps. in the first step, nitrogen and hydrogen react to form ammonia: n2(g) + 2 h_2(g) rightarrow 2 nh_3 (g) delta h = -92. kj in the second step, ammonia and oxygen react to form nitric oxide and water: 4 nh_3(g) + 5 o_2(g) rightarrow 4no(g) + 6 h_2o(g) delta h = -905. kj calculate the net change in enthalpy for the formation of one mole of nitric oxide from nitrogen, hydrogen and oxygen from these reactions. round your answer to the nearest .
