- MeO₂C. CO₂Me NaH CO₂Me MeO₂C H CO₂MeAmmonium carbamate will decompose into ammonia and carbon dioxide gasas. A 780.7 g sample of ammonium carbamate was allowed to decompose at a certain elevated temperature on a 10.0 L sealed container. A 25.0 mL sample of the headspace gas (i.e. the gas above the solid) was removed, and 0.0545 g ammonia could be isolated from that sample. NH4(NH2CO2)(s) = 2NH3(g) + CO2(g). (a) what cncenteration of ammonia, in mol/L was present in the headspace gas? (b) How many moles of ammonium carbamate had evaporated? Assume that the container volume is in addition to the volume of the solid (0.57 L) and that you may neglect the change in the volume occupied by the solid due to decomposition. (c) Calculate Kc for the decomposition of ammonium carbamate under these conditions.benzoic acid, HC-H;O: K, = 6.6 x 10-5
- Manganese sulfate forms the hydrate MnSO4⋅?H2O(s)MnSO4⋅nH2O(s) . If this hydrate is heated to a high enough temperature, H2O(g)H2O(g) can be driven off, leaving MnSO4(s)MnSO4(s) . A 10.140 g10.140 g sample of the hydrate was heated to 300 ∘C300 ∘C . The resulting MnSO4(s)MnSO4(s) had a mass of 9.0592 g9.0592 g. Calculate the value of ?n in MnSO4⋅?H2O(s)MnSO4⋅nH2O(s) .The human body burns glucose (C6H12O6) for energy according to this chemical reaction: C6H12O6+6O2→ 6CO2+6H2O 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% CO2 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 2.9kg of carbon dioxide. Calculate how many breaths it takes an average person to "exhale" 0.50kg of fat. Round your answer to the nearest thousand. You'll need to know that the density of CO2 is 2.0 kg/m^3 .The so called hydrogen economy is based on hydrogen produced from water using solar energy. The gas may be burned as a fuel: 2H2 (g) + O2 (g) ---> 2H2O (l) A primary advanatge of hydrogen as a fuel is that it is nonpolluting. A major disadvantege is that it is a gas and therefore is harder to store than liquids or solids. Calculate the volume of hydrogen gas at 25oC and 1.00 atm required to produce an amount of energy equivalent to that produced by the combustion of a gallon of octane (C8H18). The density of cotane is 2.66 kg/gal and its standard entalpy of formation is -249.9 kj/mol.
- The human body burns glucose C6H12O6 for energy according to this chemical reaction:→+C6H12O66O2+6CO26H2O. 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.mLof air, which is typically enriched to 4% CO2 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 3.0kg of carbon dioxide. Calculate how many breaths it takes an average person to "exhale" 2.00kg of fat. Round your answer to the nearest thousand. You'll need to know that the density of CO2 is 2.0/kgm3Ca2+ in a drinking water sample was analyzed by the following reactions below: Ca2+(aq) + C2O42-(aq) → CaC2O4 (s) → CaO(s) + CO(g)+ CO2(g) First an excess of C2O42- was added to 0.10 L of the Ca2+ water sample. Then CaC2O4 was precipitated, which was demcomposed into CaO with filtering and some heat. The CaO was measured to be 5.61 mg. What is the concentration of Ca2+ in the original water sample? The MW of CaO is 56.1 g/mol. 0.0100M 0.0010 M 1.00 M 0.100 M The partition coefficient (K) of methylamine (CH3NH2) is 4.50, preferring the organic layer over the aqueous layer in this extraction.
