(a)
Interpretation:
The value of x when
Concept introduction:
Thermogravimetric analysis:
Thermogravimetric analysis is a kind of thermal analysis in that temperature varies over time to determine mass of sample used for thermogravimetric analysis. This analysis provides various informations such as phase transition, desorption, absorption, chemisorption, decomposition due to thermal, oxidation and reduction. It is done on thermogravimetric analyzer. Thermogravimetric analysis is also known as thermal gravimetric analysis (TGA).
(a)
Answer to Problem 27.27P
The value of x when

To calculate: The value of x when
The reaction occurs during thermogravimetric analysis is
The formula mass of
Number of moles of
Using the stoichiometry of reaction the value of x is calculated as
(b)
Interpretation:
The uncertainty in value of x has to be calculated.
