Complete the electron pushing mechanism for the formation of the following cyclic acetal under acidic conditions by adding any missing atoms, bonds, charges, non-bonding electrons, and curved arrows. Note the use of a generic base B: that represents any basic molecule in solution, in this case another ethylene glycol.

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.
