How many grams are in 1,000 Lutheran of C2H4

How can you use chemical equations to predict the products of the reaction you can carry out?

If i add water to oil what will happen

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?
