The Boiling Point of 2-methylpropane is approximately -11.7 °C, while, Boiling Point of <span>2-iodo-2-methylpropane is approximately 100 </span>°C.

As both compounds are Non-polar in nature, So there will be no dipole-dipole interactions between the molecules of said compounds.

The Interactions found in these compounds are London Dispersion Forces.

And among several factors at which London Dispersion Forces depends, one is the size of molecule.

Size of Molecule:
                          There is direct relation between size of molecule and London Dispersion forces. So, 2-iodo-2-methylpropane containing large atom (i.e. Iodine) experience greater interactions. So, due to greater interactions 2-iodo-2-methylpropane need more energy to separate from its partner molecules, Hence, high temperature is required to boil them.

8. How much heat, in kilojoules, is needed to produce 1850 grams of ammonia (NH3),
AleksAgata [21]

Based on the enthalpy of the reaction, 41625 kJ of heat is needed to produce 1850 grams of ammonia (NH3).

<h3>What is heat of reaction?</h3>

The heat of reaction or enthalpy change is the heat absorbed or evolved when reactant molecules react to form products.

According the enthalpy value of the reaction, 4 moles of ammonia require 1530 kJ of heat for its formation.

Molar mass of ammonia = 17 g

Mass of 4 moles of ammonia = 4 × 17 = 68 g

1850 g of ammonia will require = 1850 × 1530/68 = 41625 kJ of heat.

Therefore, 41625 kJ of heat is needed to produce 1850 grams of ammonia (NH3).
