One of a substance contains the same number of molecules/atoms as in 12 grams of carbon 12

Achemical equilibrium between gaseous reactants and products is shown. n2(g) + 3h2(g) ⇌ 2nh3(g) how will the reaction be affected if the pressure on the system is increased? it will shift toward the reactant side as there is lower pressure on the reactant side. it will shift toward the product side as there is higher pressure on the product side. it will shift toward the reactant side as there are a greater number of moles of gas on the reactant side. it will shift toward the product side as there are a fewer number of moles of gas on the product side.

Consider the balanced equation below. pcl3+cl2-> pcl5 what is the mole ratio of pcl3 to pcl5
