Insoluble AgCl(s) precipitates when solutions of AgNO3(aq) and NaCl(aq) are mixed. AgNO3(aq) + NaCl(aq) AgCl(s) + NaNO3(aq) rH = ? To measure the energy evolved in this reaction, 250. mL of 0.16 M AgNO3(aq) and 125 mL of 0.32 M NaCl(aq) are mixed in a coffee-cup calorimeter. The temperature of the mixture rises from 21.15 C to 22.90 C. Calculate the enthalpy change for the precipitation of AgCl(s), in kJ/mol. (Assume the density of the solution is 1.0 g/mL and its specific heat capacity is 4.2 J/g K.)

Consider a simple mass balance model where 100 CO2 molecules are released into the atmosphere from burning fossil fuels. Half of these molecules are immediately absorbed by the terrestrial biosphere and ocean: fraction f goes to the biosphere and fraction 1-f dissolves into the ocean. Assume fossil fuel combustion consumes 1.4 molecules of O2 for every molecule of CO2 produces and photosynthesis produces 1.1 molecules of O2 for every molecule of CO2 consumed. If the observed change in oxygen is a decrease of 110 molecules, what fraction of the CO2 was absorbed by the ocean.

5 ✓7 D ✔B ✓9 ✓ 10 ✓11 12 The human body burns glucose (C,H,O,) for energy according to this chemical reaction: CH₁₂0+60-6CO₂ + 6H₂0 The products of the reaction are carbon dioxide (CO₂) and water (H₂O). Interestingly, all of the carbon dioxide and much of the water exits the body through the lungs: on every breath, the average person exhales 500 ml. of air, which is typically enriched to 4% CO, and 5% water vapor by volume. In short, when a person loses weight by dieting, the weight that is lost actually departs his body as a gas, every time he exhales. Each kilogram of body fat lost requires exhaling about 2.8 kg of carbon dioxide. Calculate how many breaths it takes an average person to "exhale" 3.00 kg of fat. Round your answer to the nearest thousand. You'll need to know that the density of CO₂ is 2.0 kg/m³. 10 13 ? D
