Consider each of the following processes and determine if work is done by the system, work is done on the system or no work is done. N2 (g) → N2 (l) 2 Na (s) + 3 H2O (l) → 2 NaOH (aq)+ H2 (g) 2 NO (g) + O2 (g) → 2 NO2 (g) 2 CH3OH (l) + 3 O2 (g) → 2 CO2 (g) + 4 H2O (g) 4 NH3 (g) + 5 O2 (g) → 4 NO (g)+ 6 H2O (g)

Which is a characteristic of the electron sea model for metallic bonding? molecular orbitals overlap to produce bands. electrons flow easily between metal nuclei. electrons are in fixed positions in the orbitals. atomic nuclei are arranged in an irregular pattern.

Match each term to its description. match term definition excess reactant a) reactant that can produce a lesser amount of the product limiting reactant b) amount of product predicted to be produced by the given reactants theoretical yield c) reactant that can produce more of the product

La reaccion entre monoxido de nitrogeno (no) y oxigeno para formardioxido de nitrogeno (no2) es un paso determinante para la formacion del smog, la reaccion es la siguiente: 2no + o2 = 2no2 cual sera el numero de moles de no2 que se formaran por la reaccion completa de 8 moles de oxigeno con suficiente monoxido?
