Question
Water can be broken down via
2 H2O (l) --> 2 H2 (g) + O2 (g)
Calculate the pressure exerted by O2 when 4.721 g of water is completely broken down and the gases are collected in a 1.947 L container at 25 oC. Hint: calculate the number of moles of O2 produced first.

When the value is opened the two gases mix and react, according to the above reaction. a) Please determine the limiting reagent and the theoretical yield. b) If the percent yield is 67.3%, what is the concentration of the product in the final reaction mixture? c) What is the partial pressure of the product in the final reaction mixture?arrow_forwardThe 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 .arrow_forward
- A chemical engineer must calculate the maximum safe operating temperature of a high-pressure gas reaction vessel. The vessel is a stainless-steel cylinder tha measures 52.0 cm wide and 62.4 cm high. The maximum safe pressure inside the vessel has been measured to be 7.00 MPa. For a certain reaction the vessel may contain up to 25.8 kg of sulfur hexafluoride gas. Calculate the maximum safe operating temperature the engineer should recommend for this reaction. Write your answer in degrees Celsius. Round your answer to 3 significant digits. temperature: C x10 Xarrow_forwardA sample of propane is placed in a closed vessel together with an amount of O2 that is 3.05 times the amount needed to completely oxidize the propane to CO2 and H2O at constant temperature.

Based L-atm on experimentally collected data, the student calculates R to equal 0.0832 mol·K L-atm Ideal gas law constant from literature: 0.08206 mol·K (a) Determine the percent error for the student's R-value. Percent error = % (b) For the statements below, identify the possible source(s) of error for this student's trial. The student notices a large air bubble in the eudiometer after collecting the hydrogen gas, but does not dislodge it. The student does not clean the zinc metal with sand paper. The student does not equilibrate the water levels within the eudiometer and the beaker at the end of the reaction. The water level in the eudiometer is 1-inch above the water level in the beaker. The student uses the barometric pressure for the lab to calculate R.arrow_forwardBelow is the equation for the combustion of methane (CH ).
