2CH3OH + ?O2 2CO2 + 4H2O
9. How many molecules of O2 are needed to balance the chemical equation?
a. 1
b. 2
c. 3
d.4

the answer would be a

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
