We do the following reaction: 2 Al(OH)3 + 3 H2SO4 Al2(SO4)3 + 6HOH If we use 13.5 g of aluminum hydroxide, A) how many moles of sulfuric acid do we need? B) How many grams of aluminum sulfate do we get? C) How many molecules of water do we get? If we obtain 8.2 g of aluminum sulfate, what is the percent yield?

a polar bond is formed when electrons are shared unevenly between atoms

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
