Lithium diisopropylamide [(ch3)2ch]2nli, referred to as lda, enjoys many uses as a strong base in synthetic organic chemistry. it is customarily prepared by the reaction of diisopropylamine [(ch3)2ch]2nh with butyllithium. draw the products of the reactions in the appropriate boxes and select the acid, base, conjugate acid, and conjugate base. be sure to answer all parts.

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 .

You may expect bonds between two atoms which each have n covalent lonic metallic hydrogen
