2. Answer the following questions about a pure compound that contains only carbon, hydrogen, and oxygen. A 0.7549 g sample of the compound burns in O2(g) to produce 1.9061 g of CO2(g) and 0.3370 g of H2O(g). Calculate the individual masses of C, H, and O in the 0.7549 g sample.Correct Answer: A. Endothermic reactions have the heat on the left side and a positive ΔH. Reactions with an increase in entropy also have a positive ΔS. Because the reaction in choice (A) produces two moles of gas for each mole of solid, it would have a positive ΔS. AP Chemistry Free Practice Question #4. 2N2O5 (g) → 2N2 (g) + 5O2 (g)
