Which among the following is used in fire extinguisher? I. Carbon dioxide II. Oxygen III. Sulphur dioxide

Which among the following is used in fire extinguisher? I. Carbon dioxide II. Oxygen III. Sulphur dioxide Correct Answer Only I

 Carbon dioxide

 As it is heavier than oxygen it cuts the contact of oxygen   with the surface

 Hence, can be used as a fire extinguisher

 Oxygen

 Cannot be used as a fire extinguisher as it helps in burning

 Sulphur dioxide

 It can’t be used because it releases toxic sulphur dioxide   gas when it is burnt

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
Which of the following statements is correct regarding the oxidation number of Oxygen? I. The oxidation number of Oxygen in most compounds is -2. II. When Oxygen is bonded to Fluorine in compounds like Oxygen difluoride and Dioxygen diflouride, the Oxygen is assigned an oxidation number of +2 and +2 respectively. III. In peroxide, an Oxygen atom is assigned an oxidation number of -1 and in Superoxide, each oxygen atom is assigned an oxidation number of -1/2.

In the question below, are given a statement followed by three courses of actions numbered I, II and III. On the basis of the information given, you have to assume everything in the statement to be true, and then decide which of the following suggested courses of actions logically follow(s) for pursuing. Statement: High-sulphur fuel oil (HSFO), essentially the leftovers of an oil refiner's output, will still flow from refineries around the world even after new rules start up in 2020 curtailing its use in the global shipping fleet.Sixty percent of the 33 refineries in a global survey will still produce HSFO in 2020 although the supply will tighten as 70 percent of these refiners plan to reduce their output.  Courses of action: I. Starting that year, ships will use marine fuel, which primarily consists of residual fuel oil, with a maximum sulphur content of 0.5 percent under International Maritime Organization (IMO) rules to reduce air pollution.  II. Currently, the global shipping fleet, which includes oil and chemical tankers as well as container ships, uses as much as 3.3 million barrels per day of HSFO with a maximum of 3.5 percent sulphur.  III. Refiners will have little incentive to produce HSFO after the regulations though some demand will remain as a small but growing number of vessels are fitted with smokestack scrubbers that remove the sulphur from the exhaust fumes and power plants will continue to consume the fuel. 
In which of the following conditions distance between molecules of carbon dioxide filled in a container may increase?
