From the data obtained from the tests, the actual boiling point lies between 34°C and 40°C.
The boiling point of a substance is the temperature at which the pressure of the substance becomes equal to atmospheric pressure. Pure substances have a sharp boiling point while impure substances boil over a temperature range.
In this case, the boiling point of the substance after 10 tests is obtained as 37+/−3°C. This implies that the actual boiling point lies between 34°C and 40°C.

Answer:
The ΔH° for the following reaction is -794 kJ, hence exothermic reaction,
Explanation:
ΔH° = ?
We are given with:
ΔH° =
(Energies required to break bonds on reactant side) - (Energies released on formation of bonds on product side)
endothermic reaction
exothermic reaction
The ΔH° for the following reaction is -794 kJ, hence exothermic reaction,
The reaction of 2 methylbutane with chlorine yield 5 monochloro derivative. Methylbutane has four carbon atoms which react with chlorine. The carbon with antibonding will be chiral and it will react with chlorine. there will be four difference group around chiral carbon hence it will have stereoisomers.
