Consider the following statements.<br>1. During the pressure of osmosis, the solvent travels from the concentrated solution to the dilute solution.<br>2. In the reverse osmosis, external pressure is applied to the dilute solution.<br>Which of the statement(s) given above is/are correct?

Correct Answer: Neither 1 nor 2

Assertion (A) In osmosis, solvent molecules pass through a semipermeable membrane from a more dilute solution to a more concentrated one, when these two are separated by the semi-permeable membrane.
Reason (R) The vapour pressure of the solvent over the dilute solution is less than that over the concentrated solution.

A man starts from point 'O', travels 20 km towards east to reach point 'A', turns right and travels 10 km to reach point 'B', turns right and travels 9 km to reach point 'C', turns right and travels 5 km to reach point 'D', turns left and travels 12 km to reach point 'E' and then turns right and travels 6 km to reach point 'F'. What is the shortest distance between point 'E' and point 'C'?

The vapor pressure of the solvent decreased by 10 mm Hg, when a non-volatile solute was added to the solvent. The mole fraction of the solute in the solution is 0.2. What should be the mole fraction of the solvent, if the decrease in vapor pressure of the solvent is required to be 20 mm Hg.?

How many liters of a 90% of concentrated acid needs to be mixed with a 75% Solution of concentrated acid to get a 30 liter Solution of 78% concentrated acid?

Two cars C and D start from the same point. C travels 9 km South, then turns to its left and travels another 11 km. D travels 3 km East, then turns Southand travels 5 km, then turns to its left and travels another 8 km. Where is D with respect to C now?

Two autos start from the same stand. Auto A travels 2 km East, then turns to its right and travels a further 3 km. Meanwhile auto B travels 5 km North, then turns West and travels 3 km, then it turns to its left and travels 8 km. Where is auto B with respect to auto A?

Two navy ships start from the same port. Ship A travels 23 km West, then turns to its left and travels 19 km. Ship B travels 19 km West, then turns North and travels 5 km, then turns to its left and travels 4 km. Where is ship A with respect to ship B?

A sample of polystyrene is warmed under reflux in concentrated nitric acid and the clear mixture is poured in water to yield a X coloured precipitate. This precipitate is then extracted with ether and then with NaOH solution followed by washing with water in each extraction. The nitro compounds from the combined final aqueous extract and alkaline extract using concentrated HCl and zinc. The final solution after being diazotized and then cooled is poured into excess of alkaline naphthol to give Y coloured solution. What are the colours X and Y?

Consider the following statements about emulsion SBR and solution SBR. I. Solution SBR has higher content of non-rubber materials than emulsion SBR II. Solution SBR has higher molecular weight but broader molecular weight distribution than emulsion SBR III. Solution SBR has higher cis-1,4-polybutadiene content than emulsion SBR Which of the following statements are true?

If the last four letters of the word 'CONCENTRATION' are written in reverse order followed by next two in the reverse order and next three in the reverse order and then followed by the first four in the reverse order, counting from the end, which letter would be eighth in the new arrangement ?
