The following chemical equation is not balanced: c3h8 + o2 co2 + h2o when this chemical equation is correctly balanced, what is the coefficient of the carbon dioxide molecule?

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?
