Concept explainers
(a)
Interpretation:
Whether the bonds of products are stronger than the bond of reactants or not needs to be determined.
Concept introduction:
It is equal to the bond energy, that is, the amount of energy required to make the bond. It is equal to the sum of bond dissociation energies of all the bonds present in the molecule.
(b)
Interpretation:
The amount of energy absorbed when 4.00 mol of glucose metabolize to form CO2 and H2O needs to be determined.
Concept Introduction:
In glucose
(c)
Interpretation:
The amount of energy absorbed when 3.00 mol of O2 reacts with glucose to form CO2 and H2O.
Concept Introduction:
In glucose metabolism bonds in glucose break to form CO2 and H2O. Bond dissociation energy is defined as the amount of energy which is required to break a chemical bond. In an endothermic reaction, energy is required but it is released in an exothermic reaction.
(d)
Interpretation:
The amount of energy absorbed when 10.0 g of glucose metabolize to form CO2 and H2O needs to be determined.
Concept Introduction:
In glucose metabolism bonds in glucose break to form CO2 and H2O. Bond dissociation energy is defined as the amount of energy which is required to break a chemical bond. In an endothermic reaction, energy is required but it is released in an exothermic reaction.

- 9.83 A student performing a calorimetry experiment combined 100.0 mL of 0.50 M HCl and 100.0 mL of 0.50 M NaOH in a coffee cup calorimeter. Both solutions were initially at 20.0°C, but when the two were mixed, the temperature rose to 23.2°C. (a) Suppose the experiment is repeated in the same calorimeter but this time using 200 mL of 0.50 M HCl and 200.0 mL of 0.50 M NaOH. Will the T observed he greater than, less than, or equal to that in the first experiment, and why? (b) Suppose that the experiment is repeated once again in the same calorimeter, this time using 100 mL of 1.00 M HCl and 100.0 mL of 1.00 M NaOH. Will the T observed he greater than, less than, or equal to that in the first experiment, and why?arrow_forwardThe chemical equation for the fermentation of glucose into ethanol is C6H12O6(s) 2 C2HsOH()+ 2 CO2(g) Using fH values at 25 C, calculate rH for this reaction. (See Question 23 for fH for glucose.)arrow_forward9.96 Most first aid "cold packs" are based on the endothermic dissolution of ammonium nitrate in water: NH4NO3(s)NH4+(aq)+NO3(aq) H= 25.69 kJ A particular cold pack contains 50.0 g of NH4NO3 and 125.0 g of water. When the pack is squeezed, the NH4NO3dissolves in the water. If the pack and its contents are initially at 24.0°C, what is the lowest temperature that this bag could reach? (Assume that the ammonium nitrate solution has a specific heat of 4.25J g-l K-l, and that the heat capacity of the bag itself is small enough to be neglected.)arrow_forward
