Consider the following statement- I. Sodium hydroxide is used to remove grease stains from cloths. II Calcium hydroxide is used in the manufacture of wax. III. Ammonium hydroxide is used in the white washing of buildings. IV. Magnesium hydroxide is used as a medicine for stomach troubles.
There are two beakers with the first containing sodium hydroxide solution and the other beaker has twice the quantity of water. To prepare a solution, 60 ml of sodium hydroxide is added to the water beaker. Three fourth of the prepared solution is again added to the first beaker. After this the first beaker has 3.5 times the solution in the water beaker. How much was the initial amount of sodium hydroxide?
When carbon dioxide gas is passed through an aqueous solution of calcium hydroxide, a white precipitate of calcium carbonates is formed, along with water. What inference can be drawn from this chemical reaction? 
Solution-1 containing 40% nitric acid and 20% carbon dioxide at the rate F combines with Solution-2 containing 30% nitric acid and 40% carbon dioxide at the rate D, the product formed contains 30% nitric acid and 20% carbon dioxide at the rate P, If P = xF what is x?
Solution-1 containing 40% acetic acid and 20% carbon dioxide at the rate F combines with Solution-2 containing 20% acetic acid and 40% carbon dioxide at the rate D, the product formed contains 30% acetic acid at the rate P, what is the percentage of carbon dioxide in product?
In the following question, the 1st and the last part of the sentence/ passage are numbered 1 and 6. The rest of the sentence/passage is split into four parts and named P, Q, R and S. These four parts are not given in their proper order. Read the sentence/passage and find out which of the four combinations is correct. 1. Global warming is the rise in average surface temperature of the earth globally. P. It is caused by the greenhouse effect of increased level of greenhouse gases. Q. Deforestation also increases carbon dioxide emissions. R. Greenhouse gases include carbon dioxide, CFCs, etc. S. The increasing use of fossil fuels is a major cause of carbon dioxide emission. 6. Carbon dioxide traps heat and causes the greenhouse effect.
In the carbonation of a soft drink, the total quantity of carbon dioxide required is the equivalent of 3 volumes of gas to one volume of water at 0⁰C and atmospheric pressure. Calculate (i) the mass fraction and (ii) the mole fraction of the CO2 in the drink, ignoring all components other than CO2 and water. Basis 1 m3 of water = 1000 kg Volume of carbon dioxide added = 3 m3 From the gas equation, pV = nRT 1 x 3 = n x 0.08206 x 273 n = 0.134 mole. Molecular weight of carbon dioxide = 44 And so weight of carbon dioxide added = 0.134 x 44 = 5.9 kg
When 10 g of calcium carbonate is decomposed completely, then 5.6 g of calcium oxide is formed along with the generation of carbon dioxide. Mass of the carbon dioxide formed is: 
A, B, C, D, E and F are six girls who use 6 different face wash – Pond’s, Lakme, Lotus, Garnier, Himalaya and Kaya (but not necessarily in the same order). They also like six different colours – Red, Blue, Brown, Peach, Black and White (also not necessarily in the same order. A and C do not like a Red colour. The girl who uses Lakme face wash likes Peach colour. The girl who likes White colour does not use Kaya nor Lotus face wash. B neither likes Peach nor Red colour. D does not like a Blue colour but uses a Lotus face wash. The girl who uses Pond’s face wash likes Red colour. C does not use Lakme face wash nor likes white colour. F neither uses Himalaya nor Kaya face wash but likes Brown colour. Who does use Himalaya’s face wash?
