i dont know did you.......
Answer:
Benzene: 37.5 Torr
Methylbenzene: 12.5 Torr
Explanation:
By Raoult's Law, each substance in a gas mixture contributes to the total pressure of the mixture proportionally to their respective mole fraction. So,
Ppartial = x*P°
Where x is the mole fraction (0.5 for each one because it's equimolar), and P° is the vapor pressure.
Benzene: Ppartial = 0.5 * 75 = 37.5 Torr
Methylbenzene: Ppartial = 0.5 * 25 = 12.5 Torr
Evidence for evolution reveals that closely related organisms have many similar physical and genetic characteristics.
Explanation:
Closely related organisms have similar physical features and genetic sequences.
When both the physical and genetic features are similar, these organisms are referred to as homologous structure.They are similar, as their evolutionary path is the same.
Example: bones from the birds and arms of the humans, have evolved more or less similarly so they are homologous structure.
In other cases, the organisms might be closely related, but their genetic structure might have a slight change. Due to this change there might be difference in the physical structure.
Example: the chimpanzee and human have different physical structure even though their evolution have taken the same path and they are closely related.
