How many sigma bonds are present? How many pi bonds are present? How many lone pairs are in the structure? What orbitals overlap to form the bond indicated by a? (e. g. sp3-sp3, write n/a if only one set) , What orbitals overlap to form the bond indicated by b? (Write n/a if only one set)

Based on the law of conservation of energy, which statement is false? answer- energy is lost when machines dont work right

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 .

Why is the structure of molecule important to its function?
