As you have asked for the Rajiv Gandhi Proudyogiki Vishwavidyalaya (RGPV) 1st semester engineering chemistry paper, I am providing you with it Write various units used for expression of hardness of water and show their interrelationship. What is boiler corrosion? Explain break point chlorination. i) Write the chemical reactions involved in lime-soda process. ii) Calculate lime and soda needed for softening of 10° litres of water containing MgSO4-120 mg/l. Mg(HCO3)2 - 14.6 mg/l, CaCl2 - 22.2 mg/l, Naci-5.85 mg/l. Or Describe and distinguish the zeolite and lime-soda processes of softening hard water Distinguish clearly between peat, lignite and brown coals. Explain the process of reforming. Calculate the amount of minimum air required for complete combustion of 1 kg of coal sample containing C-75%, H-5.2%;0-12.1%;N-4.5%and remaining ash. What is cracking and for what it is used? What are the types of cracking? Describe the working of fluid bed catalytic cracking unit. Or What is carbonization? Point out the difference between carbonization and combustion. Also describe low and high temperature carbonization RGPV Engineering chemistry paper  [IMG]https://management.ind.in/img/q/Download-RGPV-Papers-2.jpg[/IMG  ] |
