Concept explainers
(a)
Interpretation:
Whether the given reaction is endothermic or exothermic needs to be determined.
Concept Introduction :
For a reaction, if heat is required or added then reaction is endothermic and if heat is released then reaction is exothermic.
(b)
Interpretation:
The mass of glucose produced from 18.0 g of carbon dioxide needs to be determined.
Concept Introduction :
The relation between number of moles and mass is as follows:
Here, m is mass and M is molar mass.
(c)
Interpretation:
The amount of heat needed to produce 25.0 g of glucose needs to be determined.
Concept Introduction :
The relation between number of moles and mass is as follows:
Here, m is mass and M is molar mass.
