Answer:
They all wear their skeletons on the outside! This is called an exoskeleton and all creatures that have their structure on the outside are included in the phylum of Arthropods.

Answer:
The answer to your question is 126.1°C
Explanation:
Boiling point Difference of boiling points
C₃H₈ - 42.1°C
C₄H₁₀ - 0.5°C 41.6 °C
C₅H₁₂ 36.1°C 36.6°C 41.6 - 36.6 = 5°C
C₆H₁₄ 68.7°C 32.6°C 36.6 - 32.6 =4°C
C₇H₁₆ 98.4°C 29.7°C 32.6 - 29.7 = 2.9°C
We can observe on the table that the difference of boiling points diminishes 1°C when the hydrocarbon has one more carbon, then the difference of temperature between the hydrocarbon of 8 carbons and the hydrocarbon of 7 carbons must be 2°C.
So, this difference is 29.7°C - 2°C = 27.7°C.
And the boiling point of octane is approximately 98.4 + 27.7°C = 126.1°C
Answer:
0.313L
Explanation:
0.25Mx1.00L=0.80Mx V2
so, 0.25x1.00/0.80=0.313L
