Answer the following questions assuming the known reactant is used up in making the rust. Show all your work. Use the rations of reactants (ingredients) from the balanced equation4Fe + 3O2 = 2Fe2O3a. How many atoms of iron would be needed to react completely with 36 molecules of oxygen?b. How many molecules of oxygen would be needed to react completely 16 atoms of iron?c. How many moles of oxygen molecules would be needed to react with 4 moles of iron atoms?d. How many moles of iron atoms would be needed to react with 3.75 moles of oxygen molecules?
What is the energy required to change a spherical drop of water with a diameter of 1.40 mm to two smaller spherical drops of equal size?
Observe the d-orbitals on a central metal and use the character table to derive their irreducible representations (remember which column to look at). Circle any that are nonbonding for sigma interactions.
find the vapor pressure of water solution in which the molefraction of HgCl2 is 0.163 at 25 degrees celcius.
A bottle at 21.0C contains an ideal gas at a pressure of 126.4 × 103 Pa. The rubber stopper closing the bottle is removed. The gas expands adiabatically against Pexternal = 101.9 × 103 Pa, and some gas is expelled from the bottle in the process.
Calculate the pressure of the sample of gas trapped in the open-tube mercury manometer, if the atmospheric pressure is 746 mmHg and h=8.9 cm
Calculate the amount of heat that must be absorbed by 10.0 g of ice at -20°C to convert it to liquid water at 60.0°C. Given: Specific heat (ice) = 2.1 J/g·°C Specific heat (water) = 4.18 J/g·°C ?Hfus = 6.0 kJ/mol A) 420 J B) 2,900 J C) 6,300 J D) ..
When square brackets are placed around the formula for a substance, such as [NaOH], it indicates that we are working with the percent-by-mass
An aqueous solution of glycerol, C3H8O3, is 4.8 molal and has a density of 1.120 g/mL. Calculate the molarity of the glycerol solution
Disulfur dichloride is produced by reacting chlorine gas with molten sulfur. What is the percent yield if 3.25 g S2Cl2 is isolated from the reaction of 5.0 g S8 and 3.75 g Cl2
The density of water is 1.00 g/ml and the density of propanol C3H8O is 0.866 g/ml. What volume of propanol contains the same number of molecules are present in 127.1ml of water
Sulfur dioxide gas is oxidized in 50 percent excess air with 70 percent conversion to sulfur trioxide. The gases enter the reactor at 350 oC and leave at 450 oC.
Water in an enclosed vessel at 17°C contains a concentration of dissolved oxygen of 6 mg/L. At equilibrium, determine the concentration of oxygen in the space above the water in molal fraction. and the total pressure in the vessel. Henry's law con..
