In a certain experiment, 0.7000 mol of hydrogen gas reacted with 0.7000 mol of solid iodine at a constant 1 atm pressure, producing 1.4000 mol of solid hydrogen iodide and absorbing 36.9 kJ of heat in the process. Which of the following thermochemical equations correctly describes this experiment?
a. H2(g) + I2(s) → 2HI(s); ΔH° = -52.72 kJ
b. H2(g) + I2(s) → 2HI(s); ΔH° = 36.9 kJ
c. H2(g) + I2(s) → 2HI(s); ΔH° = -36.9 kJ
d. H2(g) + I2(s) → 2HI(s); ΔH° = 73.8 kJ
e. H2(g) + I2(s) → 2HI(s); ΔH° = 52.72 kJ

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.
