I, III and IV 50.0 mL of solution A are mixed with 50.0 mL of solution B and are allowed to react is The temperature of both solutions was 21.9 degree C before mixing and 30.5 degree C after mixing. The heat capacity of the calorimeter is 10.6 C, calculate the heat released by the reaction in kilojoules(kJ). For water, specific heat = 4.'18 J/g degree C and density = 1 g/ml. A. 6.048kJ B. 3.686kJ C. 2.624 kJ D. 5.650kJ E. 4105kJ In the "Chemicals of Everyday Life" experiment, which of the following gases would ten red limus paper A. HCl(g) B. H_2O(g) C. H_2(g) D. CO_2(g) E. NH_3 (g)

Explanation / Answer

7. In 8 and 10 formation of water and carboxylic acid (weak electrolyte)

8. In 8, 10 and 11 as spectator ions present on both sides thus no net ionic equation

9. 1,2,3,6 and 7 as they all form precipitate because of not being soluble in water.

10. In 4 and 5 formation of CO2 gas and in 9 formation of NH3 gas.

11. Formation of gas, water and precipitate are driving force for a reaction therefore 1, 3 and 4 are not considered driving force.

13. NH3 is basic in nature due to formation of ammonium hydroxide in aqueous solution. Other gases form acid.
