The solution to 2 questions1.a) state the assumption associated with the model used to develop the Ideal Gas Law
b) hence or otherwise describe under which physical conditions does the ideal gas law applies
2. Explain why hydrogen which has one electron in its lowest state, should in principle be a metallic conductor in its solid state whereas helium which has two electrons in its lowest energy state should be an insulator.
a 0.5224-g sample of an unknown monoprotic acid was titrated with 0.0998M of NaOH. the equivalence point of the titration occurs at 23.82ml. Determine the molar mass of the unknown acid
The liquid rate used is twice the minimum, the equilibrium relationship can be represented as yA=9.95 xA then determine what is HOG, operating line relationship, NOG and packed height of the column?
What mimimum hydronium ion concentration (M) would be needed to prevent precipitation of cupric hydroxide (Cu(OH)2 Cu2+ + 2OH- , Ksp = 2.2 x 10-20) from a solution containing 0.010 M Cu2+ ion?
If 42.3 L of PH3 forms when 85.1L of H2 (g) reacts with 167.6 (g) of P4 at STP. What is the percent yield.
Suppose that the solvent ethanol could serve to replace the methanol in this process, but at the expense of double the concentrations of the solvent in the atmosphere.
An aqueous solution is 1.00% NaCl by mass. Its density is 1.071 g/mL at 25°C. The observed osmotic pressure of this solution is 7.83 atm at 25°C.

50.0 ml of 2.00M H2SO4 react with 75.O ml of 2.00M NaOH.Identify the limiting and excess reactants.
Garlic smell is easily noticable due to the compound that is responsible for this is Allicin , when we analysed this compaound and find out molecular formula of molar mass= 486 grams
In a chemical reaction (unbalanced equation), AsF3 + C2Cl6 = AsCl3 + C2Cl2F4, the theoretical yield of C2Cl2F4 was calculated to be 1.86 mol. If the percent yield in the reaction was 77.2%.
