Solid sodium carbonate, na2co3, reacts with sulfuric acid, h2so4, to produce co2 gas according to the following equation: na2co3(s) + h2so4(aq) →co2(g) + h2o(l) + na2so4(aq) during an experiment to produce carbon dioxide gas, a student recorded the following data: p co2 = 708.1 mm hg v co2 = 29.65 ml t co2= 25.5 °c how many moles of co2 were produced?

the answer is   c.) 1575 j.

explanation:

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.

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.
