Answer:
D: chain of volcanoes circling the Pacific Basin
Explanation:
Aluminum Chloride = 133.34 g/mol
Answer is: <span> mole ratio of heptane vapor to octane vapor is </span>2,8 : 1.
p(C₇H₁₆) = 31 torr.
p(C₈H₁₈) = 11 torr.
x(C₇H₁₆) = 0,5.
x(C₈H₁₈) = 0,5.
p total = (x(C₇H₁₆) · p(C₇H₁₆)) + (x(C₈H₁₈) · p(C₈H₁₈)) = 0,5· 31 torr + 0,5·11 torr = 21 torr.
The mole fraction of heptane in the vapor is:
p(C₇H₁₆) ÷ p total) = 15,5 torr ÷<span> 21 torr = 0,74. </span>
<span>The mole fraction of octane in the vapor is:
</span>p(C₈H₁₈) ÷ p total = 5.5 torr ÷ 21 torr = 0,26.
Mole ratio heptane vapor ÷ octane vapor:
0,74 ÷ 0,26 = 2,8.
B.) Chemical properties cause chemical reactions
Hope this helps!
