Consider a 100 mol mixture that is 71.0% methane (CH4) and 29.0% ethane (C2H6). To this mixture is added 20.0% excess air. Of the methane present, 90.30% reacts, 91.80% of which forms carbon dioxide (CO2), and the balance forms carbon monoxide (CO). Of the ethane present, 86.6% reacts, 91.80% of which forms carbon dioxide, and the balance forms carbon monoxide.
1. What is the theoretical amount of oxygen required for the fuel mixture?2. What amount of air is added to the fuel mixture?3. How many moles of methane are present in the product gas?4. How many moles of carbon dioxide are present in the product gas?5. How many moles of carbon monoxide are present in the product gas?6. How many moles of water vapor are present in the product gas7. How many moles of nitrogen are present in the product gas?8. How many moles of oxygen are present in the product gas?
This solution has an osmotic pressure of 2.60 atm at 25°C. If each molecule of the solute dissociates into two particles (in this solvent), what is the molar mass of this solute?
Which of the following would be expected to have the highest pH?
During evaporation, molecules escape from the surface of a liquid and enter the gas phase. This physical change requires an energy input: a molecule cannot become gaseous unless it has sufficient energy to break free of its interactions with neigh..
In an acid/base titration, knowing that it took 13.14 mili litres of 0.1016 M sodium hydroxide, NaOH to reach the first endpoint of the titration,) from this information, mols of Phosphoric acid present in the sample is 1.335 mols.
what is your prediction for the next reaction?
In an oxidation-reduction reaction, it required 25.6 ml of a 0.65 M potassium permanganate solution to reach the equivalence point with 15.0 mL of an iron(II) sulfate solution.
Suppose that, from measurements in a microscope, you determine that a certain bacterium covers an area of 1.50 μm2
Find the Qsp if The solubility product of Ag 2 CO 3 =6.2 × 10-12. Also determine whether a precipitate forms in the solution (Assume 20 dropsper milliliter.)
Write the balanced equation for the yeast using glucose to produce energy, ethanol and carbon dioxide.
How many different signals are expected for this molecule? That is, how many magnetically different hydrogens are present in the molecule? This is in general determinted by differences in bonding, and distance to an electronegative group.
Solutions of sodium carbonate and silver (I) nitrate react to form solid silver (I) carbonate and a solution of sodium nitrate.
