Calculate the work of expansion accompanying the complete combustion of 1.0g of glucose to carbon dioxide and (a) liquid water, (b) water vapour at 20 degrees Celsiuswhen the external pressure is 1 atm
Consider the complete combustion of 1.00g of glucose to carbon dioxide and water. Calculate the work of expansion when water obtained is(a)liquid, (b)vapour at 20.0°C when the external pressure is 1.20atm.For both cases, briefly comment on the meaning of the sign/result.
Calculate the vapor pressure depression of a solution that 218 gram glucose (180.2 g/mol) is dissolved in 460 mL of water (18.01 g/mol). The temperature of the solution is 30°C. Assume the density of solution and water as 1.00 g/mL, the vapor pressure of pure water at 30°C 31.82 mm Hg.
Please show all work and explanations! Calculate ΔE, ΔS, ΔG, Q and W for the vaporization of 3.00 moles of liquid water to form water vapor at 100°C and 1.00 atm pressure. The standard molar enthalpy of vaporization of water is 40.67 kJ/mol. The density of liquid water at 100°C is 0.958 g/cm3 . Assume that the water vapor is an ideal gas, but be careful – the initial state is liquid water, so this is not simply an ideal...
Assume that an exhaled breath of air consists of 74.8% N2, 15.3% O2, 3.7% CO2, and 6.2% water vapor. a) If the total pressure of the gases is 0.985 atm, calculate the partial pressure of each component of the mixture. b) If the volume of the exhaled gas is 455mL and its temperature is 37 degrees Celcius , calculate the number of moles of CO2 exhaled. c) How many grams of glucose (C6H1206) would need to be metabolized to produce...

Calculate the work done (in Joules) when 43.3 g of Tin dissolves in excess acid at 1.05 atm and 23 degree Celsius. Assume ideal gas behavior. Sn(s) + 2H+ (aq) -> Sn2+(aq) + H2 (g)
In a closed container, one gram of water (1 cm) is boiled under constant pressure of 1 atm (1.013 10Pa) until it changes into steam. The heat of vaporization at this pressure is Lv = 2.256 x 106J/kg = 2256 J/g. Assume that water vapor behaves like an ideal gas. The temperature of the steam is 373 K, number of moles of water vapor n = 0.0546 (g mol), the ideal gas constant R = 82.057 (cm3.atm/g mol-K). (a) How...
