Sucrose decomposes in acid solution into glucose and fructose according to the first order rate law, with `t_(1/2)=3.00` hours. What fraction of sample of sucrose remains after 8 hours?

What fraction of the radioactive species (t_(1//2) = 12 "years") remains after six years ?

Consider the following statements about sucrose. I. Hydrolysis of sucrose with dilute acid yields an equimolar mixture of D-glucose and D-fructose. II. Acid hydrolysis of sucrose is accompanied by a change in optical rotation. III. In sucrose, the glycosidic linkage is between C_1 of glucose and C_2 of fructose. IV. Aqueous solution of sucrose exhibits mutarotation. Which of the statements given above are correct?

Three different solutions are prepared by dissolving 10 g each glucose, urea and sucrose in 250 mL water in separate containers. P_1, P_2, and P_3, are the respective osmotic pressures at 273K, the correct relation regarding P_1, P_2, and P_3, is

Suppose two Cars start together in the same direction from the same place. The first goes with uniform speed of 10km//hr. The second goes at a speed of 8km//hr in the first hour and increases the speed by 1//2km each succeeding hour.After how many hours will the second car overtake the first car if both cars go non-stop?

The gaseous decomposition reaction, A(g) rarr 2B(g) + C(g) is observed to first order over the excess of liquid water at 25^(@) C. It is found that after 10 minutes the total pressure of system is 188 torr and after very long time it is 388 torn The rate constant of the reaction (in hr^(1) ) is: [Given: vapour pressure of H_(2) O at 25^(@) C is 28 torr(In 2 = 0.7, In 3 = 1.1, In 10 = 2.3)]
