Question

b) Which product is insoluble and appear as solid? b) If 100 ml of 0.2M calclium chloride is mixed with 150 ml of 0.15M sodium carbonate solution, how many moles of the solid precipitate would be produced? 15) Identify each of the skeleton equations below as a synthesis, decomposition, single displacement louble displacement, or combustion reaction or neutralization reaction 1. Na + Cl2 NaCl HsPO. + Ca(OH), Ca,(PO.), + H,O 4, 3. NH, +HCl NH,CI 6, Al(OH), + HBr AIBr, 1,0 7. CHCH,CH,CH, +0,-co-HO 10.Li + AlCl3 LiC1+AI 13, Rb.p Rb + P 14.CH. + o, Co, + H,0 15. Al(OH), +H,SO AI,(SO.), + H,O

Explanation / Answer

1. synthesis   (2 reactants are forming 1 product)

2. synthesis   (2 reactants are forming 1 product)

3. neutralisation (1 acid and base recats to form salt and water)

4. neutralisation (1 acid and base recats to form salt)

5. synthesis   (2 reactants are forming 1 product)

6. neutralisation (1 acid and base recats to form salt and water)

7. combustion (reactant reacts with O2 to form CO2 and H2O)

8. synthesis   (2 reactants are forming 1 product)

9. combustion (reactant reacts with O2 to form CO2 and H2O)

10. Single displacement (Li displaces Al)

11. combustion (reactant reacts with O2 to form CO2 and H2O)

12. neutralisation (1 acid and base recats to form salt and water)

13. decomposition (1 reactant gives 2 products)

14. combustion (reactant reacts with O2 to form CO2 and H2O)

15. neutralisation (1 acid and base recats to form salt and water)
