For the reaction: N2(g) + O2(g) ⇌ 2 NO(g) Kc = 0.10 at 2000°C A reaction mixture at 2000°C initially contains [N2] = 0.200 M and [O2] = 0.200 M. Find the equilibrium concentrations of the reactants and products at this temperature.

An alkaline battery produces electrical energy according to the following equation. zn(s) + 2 mno2(s) + h2o(l) zn(oh)2(s) + mn2o3(s) (a) determine the limiting reactant if 17.5 g zn and 31.0 g mno2 are used. (type your answer using the format ch4 for ch4.) (b) determine the mass of zn(oh)2 produced. _ g

How many liters of water can be produced from 5.0liters of butane gas at stp, assuming excess oxygen? c4h10(g) + 02(g) → co2 (e) + h2o (g)
