3 molecules. 1, A chain of 3 Upper H pairs single bonded across a backbone of 1 Upper H to the left, and Upper O and Upper H to the right. 2, a chain of 2 Upper H pairs single bonded, and an Upper H pair single bonded with Upper O across a backbone of 2 Upper H single bonded. 3, a chain of 3 Upper H pairs single bonded across a backbone of 2 Upper H single bonded with 1 Upper O. List the number of each atom in the formulas above:

H

O

C

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.
