Areaction was performed in which 3.8 g of cyclohexanol was reacted with an acid catalyst to obtain 2.7 g of cyclohexene. calculate the theoretical yield for this reaction.

              Theoretical Yield =  3.11 g

               %age Yield = 86.81 %

The Balance Chemical Equation is as follow,

                    C₆H₁₂O  +  Catalyst     →     C₆H₁₀  +  H₂O  +  Catalyst

Where;

           C₆H₁₂O  =  Cyclohexanol

           C₆H₁₀  =  Cyclohexene

Calculating Theoretical Yield:

According to equation,

                100.16 g (1 mol) of C₆H₁₂O produces  =  82.15 g (1 mol) of C₆H₁₀

So,

                         3.8 g of C₆H₁₂O will produce  =  X g of C₆H₁₀

Solving for X,

                      X  =  (3.8 g × 82.15 g) ÷ 100.16 g

                      X  =  3.11 g of C₆H₁₀

Theoretical Yield =  3.11 g

Calculating %age Yield:

As,

                       %age Yield  =  Actual Yield ÷ Theoretical Yield × 100

So,

                       %age Yield  =  2.7 g ÷ 3.11 g × 100

                       %age Yield = 86.81 %

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.
