Is a electron found in a subtonic particles in a atomic nucleus

Balance this equation co2(g) + h2o (g) show that the balanced equation obeys the law if conversation of mass

The p sub shell can hold up to 8 electrons in an atom. true or false?

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?
