Question

A major component of gasoline is octane C8H18. When octane is burned in air, it chemically reacts with oxygen gas O2 to produce carbon dioxide CO2 and water H2O. What mass of carbon dioxide is produced by the reaction of 6.46g of octane? Be sure your answer has the correct number of significant digits.

Answer 1

Aus chemical Rx" 2 CG HIS + 25 0₂ - > 16CO2 +18 H₂O MW= 1148/mole auglmet from well balanced eq" :- 2 mole of CSHIG produces 16 mole of CO2 ie (2x 114) g of Cs His produces (16 444)g of co₂ : 6.46 g of Catie will produces (16 x 44 x 6.46) g of CO2 2 x 114 = 19.95g of CO2 Please Rate ...
