Consider the following equalibrium: 4NH3(g) + 3O2(g) <--> 2N2(g) + 6H2O(g). Suppose 0.30 mol of NH3 and 0.40 mol of oxygen are added to a 5.0-l container. If x mol of water is present at equalibrium, how many moles of ammonia will remain at equalibrium? Moles of NH3=?
considering the given equation fe2o3 s 3 co g ? 2 fe s 3 co2 g this is the overall reaction for the production of
What volume of oxygen is required to burn completely 401 cm3 (centimeters cubed) of butane, C4H10 (All substances are gases measured at the same temperature and pressure.)
Calculate the activity for CS2 at mole fraction= .722 for a Henry's Law standard state using the following data: 446.9 Torr and kH(CS2)=1750 Torr
The mass of a cube of iron is 379 g. Iron has a density of 7.87 g/cm3. What is the mass of a cube of lead that has the same dimensions?
The total mass of solid unknown dissolved in the sample was 0.1200 g. If the sample were dissolved to a final volume of 100.0 mL, and a 25.00 mL sample of the solution required 36.32 mL of EDTA solution, find the mass percent of CaCO3 that was pre..
When a 2.691 g sample of the unknown organic compound is vaporized at 90.0(degrees)C and 708. mmHg it is found to occupy a volume of 1.00L.
One of the highest concentrations of peroxyacyl nitrates has been found in the Los Angeles (LA) basin at 30 ppb, reaching its peak at mid-afternoon. Most of the pollution in the LA basin is created in an area of only 3000 km^2
Determine the adiabatic flame temperature (C). Assume product temperatures of 1500K and 3000K, and then linearly interpolate.
Lithium will react with oxygen in a pressurized container to produce solid lithium oxide at 25°C. if 0.130 g Li(s) is placed in a 0.500 L container filled with oxygen at 1.90 atm
