Which one of the following statements is not true/false?<br>1. An acid that is completely ionized with ions produces large amounts of H<sup>+</sup> ions. for example HCl, H2SO<sub>4</sub>, HNO<sub>3</sub><br>2. A weak acid that is partially ionized in water produces small amounts of H<sup>+</sup> ions. for example - CH<sub>3</sub>COOH, H<sub>2</sub>CO<sub>3</sub>, H<sub>2</sub>SO<sub>3</sub>

Correct Answer: Both 1 and 2 are correct

Which of the following statements is true/false?
1. An alkali that is completely ionized in water produces a large number of OH- ions. For example NaOH, KOH
2. An alkali that is partially ionized in water produces a large number of OH+ ions. For example KOH

Large, medium and small ships are used to bring water. 4 large ships carry as much water as 7 small ships, 3 medium ships carry the same amount of water as 2 large ships and 1 small ship. 15 large, 7 medium and 14 small ships, each made 36 journeys and brought a certain quantity of water. In how many journeys would 12 large, 14 medium and 21 small ships bring the same quantity ?

In a batch process, the reaction takes place in the presence of an acid medium. The acid is drained from the reaction vessel at the rate of 15ml/s as a result of the density difference of the acid from the reacting component. To avoid wastage of acid, it is recycled to an acid tank which has 1000 L capacity. The acid drained from the reaction vessel, picks up 50 g/L solids from the reactor. Acid is fed once again to the process from acid tank. When the process is started, the acid is almost pure in the tank as a result of filtration. As the reaction proceeds, acid in the tank gets more and more contaminated with the solids. The concentration of the solids should not exceed 100 g/L from the process point of view. The batch time is 16h. Estimate whether the concentration of the solids will exceed 100g/L during the batch reaction.

2 large and 1 small pumps can fill a water tank in 4 hours. One large and 3 small pumps can also fill the same water tank in 4 hours. how many hours will it take for 3 large and 4 small pumps to fill the tank?

2 large and 1 small pumps can fill a water tank in 4 hours. 1 large and 3 small pumps can also fill the same water tank in 4 hours . How many hours will it take for 3 large 4 small pumps to fill the tank?

Read the following passage carefully and choose the most appropriate answer to the question out of the four alternatives.
Most economists in the United States seem captivated by the spell of the free market. Consequently, nothing seems good or normal that does notaccord with the requirements of the free market. A price that is determined by the seller or, for that matter (for that matter: so far as that isconcerned), established by anyone other than the aggregate of consumers seems pernicious. Accordingly, it requires a major act of will to thinkof price-fixing (the determination of prices by the seller) as both "normal" and having a valuable economic function. In fact, price-fixing is normalin all industrialized societies because the industrial system itself provides, as an effortless consequence of its own development, the price-fixingthat it requires. Modern industrial planning requires and rewards great size. Hence, a comparatively small number of large firms will be competingfor the same group of consumers. That each large firm will act with consideration of its own needs and thus avoid selling its products for morethan its competitors charge is commonly recognized by advocates of free-market economic theories. But each large firm will also act with fullconsideration of the needs that it has in common with the other large firms competing for the same customers.

A right circular cylinder is partially filled with water. Two iron spherical balls are completely immersed in the water so that the height of the water in thecylinder rises by 4 cm. If the radius of one ball is half of the other and the diameter of the cylinder is 18 cm, then the radii of the spherical balls are
