A 51 kg person drinks 400. g of milk, which has a "caloric" value of approximately 3.0 kJ/g. If only 15% of the energy in milk is converted to mechanical work, how high (in meters) can the person climb based on this energy intake? [Hint: The work done in ascending is given by mgh, where m is the mass (in kilograms), g the gravitational acceleration (9.8 m/s2), and h the height (in meters.)]
If the endpoint is surpassed in the back-titration with NaOH, will the reported amount of antacid in the sample be too high or too low?
CS2(l) + 3 O2(g) -→ CO2(g) + 2 SO2(g) . If 1.18 mol of CS2 is combined with 1.55 mol of O2, identify the limiting reactant.
An 8 g of SO3 was placed in an evacuated container where it decomposed at 600 degrees Celsius. At equilibrium, the total pressure and density were 1.8 ATM and 1.6 g/L. Calculate constant pressure.
