Cal the molarity of solution prepared by dissolving 250 of ca(no3)2 to make 2.5l of solution

Drive down any three characteristic of modern periodic table

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?

Why is the structure of molecule important to its function?
