Problem 101AE

(a) When a $$0.235-g$$ sample of benzoic acid is combusted in a bomb calorimeter (Figure 5.19), the temperature rises $$1.642^{\circ} \mathrm{C}$$. When a $$0.265-g$$ sample of caffeine, $$\mathrm{C}_8\mathrm{H}_{10}\mathrm{O}_2\mathrm{N}_4$$, is burned, the temperature rises $$1.525^{\circ} \mathrm{C}$$. Using the value $$26.38 \ kJ/g$$ for the heat of combustion of benzoic acid, calculate the heat of combustion per mole of caffeine at constant volume.(b) Assuming that there is an uncertainty of $$0.002^{\circ} \mathrm{C}$$ in each temperature reading and that the masses of samples are measured to $$0.001 \ g$$, what is the estimated uncertainty in the value calculated for the heat of combustion per mole of caffeine?

Chemistry Chapter 1 Notes Chemistry— the study of Matter Hypothesis— a tentative explanation for a series of observations. Theory— a model with which one is able to explain and make a further prediction about natural phenomena. Natural law— a concise statement, often in mathematical terms, that summarizes observations of certain natural phenomena. The form of reasoning in which a general statement or natural law is inferred from a set of observations is called induction. Building Blocks of Matter: Subatomic particles(make up the atom):  Protons(positively charged)  Neutrons(No charge)  Electrons(negatively charged) Electrons are a type of lepton Protons and neutrons are made of quarks Atoms combine to make molecules
