HOLIDAY HOMEWORK CLASS XI English Physics Chemistry Design a cover page of the Novel Canterville Ghost. Write the character sketch of Mr. Otis, Virginia and Sir Simon-de-Canterville (Caterville Ghost). Prepare an investigatory project and its report with conclusion about any topic from the syllabus. Q.1 Given the following reaction: Na 2S 2O 3 + AgBr NaBr + Na 3[Ag(S 2O 3) 2] a. How many moles of Na 2S 2O 3 are needed to react completely with 42.7 g of AgBr? b. What is the mass of NaBr that will be produced from 42.7 g of AgBr? Q2. KO 2 is used in a closed-system breathing apparatus. It removes carbon dioxide and water from exhaled air. The reaction for the removal of water is: KO 2 + H 2O O 2 + KOH. The KOH produced is used to remove carbon dioxide by the following reaction: KOH + CO 2 KHCO 3. a. What mass of KO 2 produces 235 g of O 2? b. What mass of CO 2 can be removed by 123 g of KO 2? Q3. Sb 2S 3(s) + 3Fe(s) 2Sb(s) +3FeS(s) If 3.87 10 23 particles of Sb 2S 3(s) are reacted with excess Fe(s), what mass of FeS(s) is produced? Q4. 7.95 gram of cupric oxide was reduced by heating in a current of hydrogen and the weight of copper that remained was 6.35 gram. In another experiment, 19.05 gram of Cu was dissolved in the nitric acid and the resulting copper nitrate is converted into cupric oxide by ignition. The weight of cupric oxide formed was 23.85 gram. Show that these results illustrate the law of constant composition. Q5. Two compounds each containing only tin and oxygen had the following composition. Mass % of Tin Mass % of oxygen Compound A 78.77 21.23 Compound B 88.12 11.88 Show that these data illustrate the law of multiple proportion? Q6. 4 gram of a mixture of CaCO3 and Sand (SiO2 ) is treated with an excess of HCl and 0.88 gm of CO2 is produced. What is the percentage of CaCO3 in the original mixture? Q7. 44 gram sample of a natural gas, consisting of methane [CH4 ] and ethylene [C2H4 ] was burned in excess of oxygen yielding 132 gm CO2 and some H2O as products. What is the mole % of ethylene in the sample? Q8. P and Q are two elements which form P2Q3 and PQ2 molecules. If 0.15 mole of P2Q3 and PQ2 weighs 15.9 g and 9.3g, respectively, what are atomic mass of P and Q? Q9. How many g of HCl is needed for complete reaction with 69.6 g MnO2? In the reaction
