3860.	Benzene and toluene both have equal mole fraction in their mutual solution. what do you except about their mutual solution. what do you except about their mole fraction in vapour phase at same temperature(given p°benzene =3p°toulene)
Answer» Answer: Explanation: For SOLUTION A, the mole fractions of toluene and benzene are equal which COMES out to be 0.5 each. The partial pressure of toluene in the vapor phase is P T =P T 0 X T =60 mm Hg×0.5=30mmHg. Here, P T 0 is the vapor pressure of pure toluene and X T is the mole FRACTION of toluene in liquid phase. The partial pressure of benzene in the vapor phase is P B =P B 0 X B =160 mm Hg×0.5=80mm Hg. Here, P B 0 is the vapor pressure of pure benzene and X B is the mole fraction of benzene in liquid phase.

The molar masses of benzene and toluene are 78.11 g/mol and 92.14 g/mol respectively. Let 78.11 g of benzene and 78.11 g of toluene are present in the mixture. This corresponds to 1 mole of benzene and 0.847 mole of toluene. The mole fractions of benzene and toluene are 0.5412 and 0.4588 respectively. The partial pressure of toluene in the vapor phase is P T =P T 0 X T =60mmHg×0.4588=27.53mmHg. Here, P T 0 is the vapor pressure of pure toluene and X T is the mole fraction of toluene in liquid phase.

Therefore V = 50 x 0.1/0.01= 500 ml. So the amount of water to be added to 50 ml.of deci normal Solution. = (500- 50)= 450 ml.

ANSWER:

Volume of deci normal Solution= 50 ml. Concentration of DECINORMAL Solution=0.1N Volume of centi normal Solution= V concentration of centinormal Solution=0.01. So V x 0.01 = 50 x 0.1. Therefore V = 50 x 0.1/0.01= 500 ml. So the amount of water to be added to 50 ml.of deci normal Solution. = (500- 50)= 450 ml.

Answer» Explanation: A nitrate test is a chemical test used to determine the presence of nitrate ion in solution. TESTING for the presence of nitrate via wet chemistry is generally difficult compared with testing for other anions, as ALMOST all nitrates are soluble in water. In contrast, many common ions give insoluble salts, e.g. halides precipitate with silver, and sulfate precipitate with barium. The nitrate anion is an oxidizer, and many TESTS for the nitrate anion are based on this property. Unfortunately, other oxidants present in the analyte may interfere and give erroneous results.The reaction for the given Brown ring test is given below:- 6Feso4 + 3H2SO4 + 2HNO3 -> 3FE2(SO4)3 + 4H2O + 2NO please mark as brainliast
