If 5.00 grams of iron react in the presence of excess sulfuric acid, how many grams of iron (II) sulfate are formed?

Acovalent bond is formed between the two hydrogen bonds

The answer is d- principle of faunal succession.

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 -
