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

The question below consists of a set of labelled sentences in which first and the last sentence is given. Out of the four options given, select the most logical order of the sentences to form a coherent paragraph. S1- Climatic changes have become more prominent now because of global warming which is a global concern. P- Such gases never let sun rays to go back to the atmosphere, however, trap heat from them.  Q- The release of various greenhouse gases in the atmosphere by many natural means and human activities causes an increase in atmospheric temperature because such gases have a capability to absorb all the heat of environment from the sun, burning coal, etc. R- Both are hot issues of the current time and it is the time to analyse causes and prevention methods to prevent global warming.  S- Fossil fuels burning release more carbon dioxide which is increasing day by day because of deforestation.  S6- Plants are the main source to utilize carbon dioxide as a food, however, we are disturbing the natural cycle by cutting more plants.
Various gases present in air are oxygen, nitrogen, argon and neon. The boiling points of these gases are –183, –196, –186 and –246 degrees Celsius, respectively. These gases are separated from each other by the process of fractional distillation. Which of the following statements about the order in which these gases get separated is correct?
Rearrange the given 5 sentences A, B, C, D and E in proper sequence to form a meaningful paragraph and mark the correct sequence from the given options as your answer. It is caused due to the greenhouse effect of increased level of green house gases such as carbon dioxide, CFCs, etc. There are various types of pollutants also which involved in increasing the atmospheric temperature of the earth. Water vapor is also a significant greenhouse gas which is not directly produced by humankind but involve in global warming hugely. Global warming is a gradual increase in the temperature of the earth surface and atmosphere all around the world. Increasing use of fossil fuels by the people and deforestation is increasing carbon dioxide emissions which trap heat and cause greenhouse effect.
