For crude oil, if 3.75 x 106g of carbon dioxide are produced for each kilocalorie of energy released, how many kilograms of carbon dioxide are released when a full barrel is burned?

Ithink it’s 3 as the answer.

I’m really not sure what’s the answer. sorry

Answer is: the equilibrium  shifts toward the reactants, to the left side of chemical reaction.it is because lead(ii) nitrate dissociates in water: pb(no₃)₂ → pb²⁺(aq) + 2no₃⁻(aq).according to lechatelier's principle, the position of equilibrium moves to counteract thechange (more lead cations, common ion), the position of equilibrium will move so that the concentration ofproducts decrease and concentration of reactants of chemical reaction increase.read more on -
