Answer:

Starch

Explanation:

Pasta is made of eggs and flour. The eggs are basically water, proteins and fats while flour is composed by starch.

Starch is a macromolecule that is composed of two polysaccharides, amylose and amylopectin, which are big chains of glucose, so starch is a carbohydrate. Carbohydrates are the biggest source of energy to the body, then, the starch will be the molecule in the pasta that increases the runner’s energy.

Bear in mind that proteins and fats also give energy but, as the starch is in greater proportion it will provide more energy to the runner.

A reaction was performed in which 4.0 g of cyclohexanol was reacted with an acid catalyst to obtain 2.8 g of cyclohexene. calcul
ioda

Answer:

              %age Yield  =  85.36 %

Solution:

The Balance Chemical Reaction is as follow,

               C₆H₁₂O  +   Acid Catalyst    →    C₆H₁₀  +  Acid Catalyst + H₂O

According to Equation ,

              100 g (1 mole) C₆H₁₂O produces  =  82 g (1 moles) of C₆H₁₀

So,

                       4.0 g of C₆H₁₂O will produce  =  X g of C₆H₁₀

Solving for X,

                      X =  (4.0 g × 82 g) ÷ 100 g

                      X  =  3.28 g of C₆H₁₀   (Theoretical Yield)

As we know,

                     %age Yield  =  (Actual Yield ÷ Theoretical Yield) × 100

                     %age Yield  =  (2.8 g ÷ 3.28 g) × 100

                     %age Yield  =  85.36 %
