Question

Part A
A sample of sodium reacts completely with 0.568 kg of chlorine, forming 936 g of sodium chloride. What mass of sodium reacted?
Part B
When Carbon is burned in air, it reacts with oxygen to form carbon dioxide. When 27.6 g of carbon were burned in the presence of 89.6 g of oxygen, 16.0 g of oxygen remained unreacted. What mass of carbon dioxide was produced? Part A

Explanation / Answer

part-A

Na + 1/2 Cl2 -------------------------> NaCl

generally

35.5 grams of chlorine combines with sodium gives ------------------------------------58.5 g of NaCl

? g of chlorine cobines with sodium gives----------------------------------------------936 g of sodium chloride

                                           = 936*35.5/58.5

                                              = 568 g of chlorine

thereforE

23 grams of Na react with--------------------------------35.5 grams of chlorine

? grams of Na reacted ---------------------------------568 g of chlorine

              = 568*23/35.5

              = 368 g of sodium reacted

part-B

C + O2------------------------> CO2

THE AMOUNT OF OXYGEN REACTED = 89.6-16.0= 73.6 g of O2

32 grams of oxygen combines with carbon ------------------------------------------44 g of CO2

73.6 grams of oygen combines with carbon gives ------------------------------- ? grams of CO2

                       = 73.6*44/32

                        = 101.2 g of CO2
