A particular kind of Spanish orange is completely fat free. If one of the oranges has 40 Calories total and a test shows that it contains 1gram of protein, how many grams of carbohydrates does it have

                      9 grams of Carbohydrates

Explanation:

                     The energies contained by each class of these compounds are as;

(i)  Fats:

            1 grams of Fat contains 9 Calories

(ii)  Proteins:

            1 grams of Proteins have 4 Calories

(iii)  Carbohydrates:

            1 grams of Carbohydrates contains 4 Calories

(iv)  Vitamins and Minerals:

            Vitamins and Minerals have no Calories

Solution:

As 1 gram of Protein Contains 4 Calories so, we will subtract 4 Calories from the total Calories contained by the Juice as,

Calories by Carbohydrates  =  Total Calories - Calories by Protein

Calories by Carbohydrates  =  40 - 4

Calories by Carbohydrates  =  36 Calories.

Hence,

As,

           4 Calories were contained by  =  1 gram of Carbohydrate

So,

       36 Calories will be contained by  =  X grams of Carbohydrates

Solving for X,

                      X =  36 Calories × 1 gram / 4 Calories

                       X  =  9 grams of Carbohydrates

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
