Efficiency of the ram is calculated by dividing the work done by the work or energy that is exerted to do so. This is calculated through the equation,

     S = ((Wout) / (Win)) x 100%

Substiuting the known values to the equation.

    S = (153 J)/(185 J) x 100%

Efficiency = 82.7%.

Based on lewis structure analysis, what is the formal charge of the central atom in clf3
MArishka [77]
Formal Charge is calculated as, Lewis structure is attached below,

Formal Charge  =  [# of valence electrons] - [electrons in lone pairs + 1/2 the                                     number of bonding electrons]

# of valence electrons of Cl  = 7

electrons in lone pairs  =  4

number of bonding electrons  =  6

Formal Charge  =  [7] - [4 + 6/2]

Formal Charge  =  [7] - [4 + 3]

Formal Charge  =  [7] - [7]

Formal Charge  =  0

Result:
           Formal charge on Cl in ClF₃ is zero.
