Consider the following combustion reaction: 2 C4H10 + 13 O2 --> 8 CO2 + 10 H2O. 251 of C4H10 react with 155 g of O2 a) which substance is the limiting reactant? b) what mass of CO2 and H2O can be produced? Please help me...

a) the particles of the chair are strongly held together.

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.
