Enthalpy question. please help me ASAP
1) Draw a graph of AcH (vertical axis) against the number of carbon atoms in one molecule and
use it to estimate a value for the enthalpy change of combustion of pentan-1-ol under the same
conditions.
i Extrapolate the graph line to 0 on the x-axis and comment on the value of AH you read off from
the graph.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
