There are 20 kg of exhaust gas formed per kg of fuel oil burned in the combustion of diesoline C16H32. What is the excess air percent.
WhalefossilsfoundintheSaharaDesertprovetheregionwasoncecoveredin water. Remnants of that water, called “fossil water,” still exist today in the Nubian Sandstone Aquifer System (NSAS). The NSAS is the world’s largest body of fossil water, containing an estimated 1.65 x 1014 tons. Given the density of water as 1.00 g/mL, what is the NSAS’s volume? Is the NSAS bigger or smaller than Lake Michigan (estimated at 5.0 x 1018 cm3)? (1 ton=2000 pounds exactly) (1 pound=0.454 kg)
(a) Find the density in SI units of air at a pressure of 1.00 atm and a temperature of 20 °C , assuming that air is 78% N2, 21% O2, and 1% Ar , (b) Find the density of the atmosphere on Venus, assuming that it’s 96% CO2 and 4% N2 , with a temperature of 737 K and a pressure of 92.0 atm.
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/kgm3
A gaseous compound of phosphorus (P) and fluorine (F) was found to have a density of 3.50 g L' at a temperature of 25.0 °C and a pressurc of 740 tor. It was also found to consist of 35.2% P and 64.8% F in a volume of 1 L. Assume that the mass of the sample is 100.0 g. Determine a) (i) its empirical formula (ii) its molecular mass using its empirical formula stated in part (i) (iii) its molecular mass using ideal gas law (iv) its molecular formula. Explain why the molecular formula is same as empirical formula. Given that the molecular mass of P is 30.97 g mol'; the molecular mass of F is 19 g mol'; 1 atm = 760 torr

Fertilizer calcium cyanamide reacts with water forming calcium carbonate and releasing ammonia gas according to the following (non-balanced) equation: CaCN2(s) + H2O => CaCO3(s) + NH3(g)From 7.70 g of CaCN2, by this reaction, 3.10 L of ammonia gas were collected at standard temperature & pressure. What was the percent yield of this process? (A) 40% (B) 67% (C) 83% (D) 93% (E) None of those. If so what is your answer?

The human body burns glucose (C6H₁₂O) for energy according to this chemical reaction: 12 C6H12O6 +60₂ 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 2.8 kg of carbon dioxide. Calculate how many breaths it takes an average person to "exhale" 0.50 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.
