Answer:
It's called the circle of fifths because each key signature is separated by the distance of a fifth interval (for example: C to G on the circle above represents a fifth). it was help full because Use the circle of fifths to recall how many sharps or flats each key signature has, and to understand which major and minor keys are relative (or share the same key signature).

Answer:
7.2 moles
Explanation:
Given the equation:
C2H6 + O2 → CO2 + H2O
First step is to balance the equation:
For complete combustion of ethane :
2C2H6 + 7O2 → 4CO2 + 6H2O
From the equation above, Mole ratio of ethane to CO2 ;
2C2H6 : 4CO2
2 : 4, reducing to lowest term; 1 : 2
Thus ;
1 mole C2H6 - - - - > 2 moles CO2
Therefore when ;
3.6 moles C2H6 - - - - > x moles CO2
x - - - - > (2 × 3.6) moles
x - - - > 7.2 moles
Therefore,
3.6 moles C2H6 = 7.2 moles CO2
I don't trust you after the last one ...
