Air-activated hand warmers consist of an iron powder contained in a porous pouch. When the pouch is removed from its air-tight packaging, oxygen from the air enters the pouch and reacts with the iron to produce iron(III) oxide. Construct an explanation for why the pouch gets hot based

on changes in total bond energy.

You can still be friends with each other. you don't have to date since he likes someone else. just stick to being friends for now

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 -
