Between A and B

  • The reaction is spontaneous
  • Means reaction is happening by itself.
  • So randomness of A and B is increasing .

The highest probability is that A and B are solids and they are forming liquid or gases.

Between A and C

  • The reaction is non spontaneous
  • Randomness of particles is decreasing.

Highest probability is that A and C are gases and they are turning into liquid or solid

Hexane and hexene are hydrocarbon compounds from different homologous series. the combustion of these two compounds produce diff
AURORKA [14]

Answer:

Percentage of carbon of alkene is higher compared to the alkane that has the same number of carbon per molecule. Because of this, combustion of alkene will produce more sooty flame compared to their corresponding alkane and because Alkenes have a higher percentage of carbon compared to their corresponding alkane.

Explanation:

Relative atomic mass : C= 12 and H=1

Percentage of Carbon Hexane (C6H14)

Percentage of Carbon = 83.7 percent

6(12) x 6(12) +14(1) x 100 percent= 83.7 percent

Percentage of Carbon Hexene = 85.7 percent
