As an epa scientist studying catalytic converters and urban smog, you want to find kc for the following reaction: 2no2(g) ⇋ n2(g) + 2 o2(g) kc = ? . use the following data to find the unknown kc (1) ½ n2(g) + 1/2 o2(g) ⇋ no(g) kc = 4.8x10-10 (2) 2no2(g) ⇋ 2no(g) + o2(g) kc = 1.1x10-5

When you perform this reaction, what could remain at the end of the reaction? check all that apply. excess reactant aqueous copper chloride excess reactant aluminum oxygen product solid copper carbon dioxide product aqueous aluminum chloride water
