Explain Solid State Chemistry, 1) Write the balanced chemical equation for Fe2O3+2Al?2Fe+Al2O3 using the lowest possible whole number coefficients.
You are given trhat 0.01 m aqueous solutions of each of the given solution as, C6H12O6, K3PO4, CaCl2 , NaI you jutst need to place the given solutions in order of increasing change in the freezing point of the solution.
Water is added to 25.0 mL of a 0.776 M KNO3 solution until the volume of the solution is exactly 500 mL. What is the concentration of the final solution.
A compound is analyzed and found to contain 12.1% carbon, 16.2% oxygen, and 71.7% chlorine (by mass). Calculate the empirical formula of this compound.
Using extraction techniques how would you separate a mixture of aniline and toluene using dichloromethane as the extraction solvent?
At 373 K, Keq = 2.39 for the following reaction: SO2Cl2(g) = SO2(g) + Cl2(g) In an equilibrium mixture of the three gases, the partial pressures of SO2Cl2 and SO2 are 3.31 atm and 1.59 atm, respectively.
The system CO2(g) + H2(g) *) H2O(g) + CO(g) is at equilibrium at some temperature. At equilibrium a 4.00 L vessel contains 1.00 mole CO2, 1.00 mole H2, 2.40 moles H2O, and 2.40 moles CO.
A packed tower is used to purify a gas containing 4 mole % of H2S. The total inlet gas flow to the tower is 75 kmol/h and the total inlet pure solvent flow to be used to absorb the H2S is 95 kmol /h.
suppose the condenser operates as a total condenser at 40 degrees, the production rate of the overhead product is 75kmol/h. The ratio of reflux and overhead product is 1.5:1.
If 132 mL of wet H2 is collected over water at 24°C and a barometric pressure of 736 torr, how many grams of Zn have been consumed?
how many grams of benzene are needed in 46.3 grams NaBr (103 g/ mol)? the freezing point of solution to 3.94 degree C?
