What is the moles of 4.48 l of co2 at stp ?

From the molar gas volume 1 mole of a gas at standard temperature and pressure occupies a volume of 2.24 liters. Therefore;                                           1 mole of CO2 = 2.24 liters; thus;                                                                                  4.48 L will have;  4.48/2.24 = 2 moles                                                            Hence, 2 moles of CO2 at STP will occupy a volume of 4.48 L

Answer:

a. energy is absorbed in the reaction.

explanation:

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.
