A 20.753 g sample of aqueous waste leaving a fertilizer manufacturer contains ammonia. The sample is diluted with 74.741 g of water. A 11.441 g aliquot of this solution is then titrated with 0.1094 M HCl. It required 29.22 mL of the HCl solution to reach the methyl red endpoint. Calculate the weight percent NH3 in the aqueous waste.
VO2 can exist in insulating or metallic form, depending on temperature and pressure.
27.5 grams of hydrogen chloride is dissolved into 70.0 ml of water. Calculate the mole fraction for the hydrogen chloride that is dissolved in the water.
Suppose that Mt=Lt=0.1M (exactly) and the pH is somehow fixed at 5.00. (This means that the charge balance no longer applies.) Use the equilibria and the two mass balances to find the concentrations of ML+, M+2, L-, HL.
How many grams of NaOH are in a 225.0 mL sample of a 2.5 M solution of NaOH? (Molar mass of NaOH is 40.0 g/mol)
Consider the reaction 2NO2(g)--> N2O4(g). Go = -5.40 kJ at 298K. (b) Calculate delta G at 298K if partialpressures of NO2 and N2O4 are 0.36 atm and 1.60 atm
Calculate the molality of the unknown compound (m). m=mol of solute X particles per formation / mass of solvent , kg Data given: Mass of test tube , flask, t-butyl alcohol and unknown
Calculate the molecular weight of the unknown acid.
Pre-Lab Assignment- Understanding Activity 3 in this manual and significant figures and uncertainty in measurements in general will help you answer the last two questions
If a reaction mixture initially contains 0.159 M SO2Cl2 , what is the equilibrium concentration of Cl2 at 227 C?
Calculate the minimum chloride ion concentration needed to initiate precipitation of PbCl2 from a solution that contains 0.01M Pb^2+ (aq).
At a certain temperature and pressure 2.8 L of N2 reacts with 4.2 L of O2. If all the N2 and O2 are consumed, what volume of N2O3, at the same temperature and pressure, will be produced?
Radiochemical techniques are useful in estimating the solubility product of many compounds. In one experiment, 50.0 mL of a 0.010 M AgNO3
