Which equation represents a decomposition reaction?
(1) caco3(s) ==> cao(s) + co2(g)
(2) cu(s) + 2agno3(aq) ==> 2ag(s) + cu(no3)2(aq)
(3) 2h2(g) + o2(g) ==> 2h2o(l)
(4) koh(aq) + hcl(aq) ==> kcl(aq) + h2o(l)

Consider the reaction: n2(g) + o2(g) ? 2no(g) kc = 0.10 at 2000oc starting with initial concentrations of 0.040 mol/l of n2 and 0.040 mol/l of o2, calculate the equilibrium concentration of no in mol/l how would this be done?
