False,it could be false information like Wikipedia
Answer:
Part a)
Part b)
Explanation:
As we know that capacitor plate is connected across 2.1 V and after charging it is disconnected from the battery
So here we can say that charge on the plates will remain conserved
So we will have
now dielectric is removed between the plates of capacitor
so new potential difference between the plates
Part b)
Now the capacitor plates are again isolated and unknown dielectric is inserted between the plates
So again charge is same so potential difference is given as
1. 2 C2H6 + 7 O2 = 6 H2O + 4 CO2
Conduction is a mode of transfer of heat there
