Concept explainers
(a)
Interpretation: The kilojoules of heat released when 2.00 g of Fe reacts should be calculated.
Concept Interpretation: The number of moles can be calculated using the following relation:
Here, m is mass in grams and M is molar mass is g/mol.
If amount of heat required from 1 mol is given, it can be calculated for any number of moles by unitary method.
(b)
Interpretation: The mass of rust form when 150 kJ of heat is released should be calculated.
Concept Interpretation: The number of moles can be calculated using the following relation:
Here, m is mass in grams and M is molar mass is g/mol.
If amount of heat required from 1 mol is given, it can be calculated for any number of moles by unitary method.
