Types of Bonds can be predicted by calculating the difference in electronegativity.
If, Electronegativity difference is,

                Less than 0.4 then it is Non Polar Covalent
                
                Between 0.4 and 1.7 then it is Polar Covalent 
            
                Greater than 1.7 then it is Ionic

For C and N,
                    E.N of Nitrogen      =   3.04
                    E.N of Carbon        =   2.55
                                                   ________
                    E.N Difference             0.49          (Weakly Polar Covalent)

For N and S,
                    E.N of Nitrogen      =   3.04
                    E.N of Sulfur          =   2.58
                                                   ________
                    E.N Difference             0.46           (Weakly Polar Covalent)

For K and F,
                    E.N of Fluorine       =   3.98
                    E.N of Potassium   =   0.28
                                                   ________
                    E.N Difference             3.70          (Ionic)

For N and N,
                    E.N of Nitrogen      =   3.04
                    E.N of Nitrogen      =   3.04
                                                   ________
                    E.N Difference             0              (Non Polar Covalent)

A pharmaceutical company is making a large volume of nitrous oxide (NO). They predict they will be able to make a maximum amount
iragen [17]

Answer:

The answer is "Option B"

Explanation:

From the query, the following knowledge is derived:  

Yield in percentage = 47%  

Performance of theory = 4860 g  

Actual yield Rate =?  

The percentage return is defined simply by the ratio between both the real return as well as the conceptual return multiplied by the 100. It's also represented as numerically:

Rate = \frac{Existing \ Rate} {Theoretical \ Rate} \times 100

Now We can obtain the percent yield as followed using the above formula:  

\text{Yield in percentage}= \frac{Actual \ yield \ Rate} {Theorical \ Rate} \times  100

47\% = \frac{Actual \ yield \ Rate}{4860}

The value of the Actual yield Rate =47\% \times 4860

                                                        = \frac{47}{100} \times 4860 \\\\ = 2284.2 g

The Actual yield Rate= 2284.2 g.
