The nutritional information label for food items provides the calorie content and other nutritional data for each serving of an item. Carbohydrates provide about 17 k/g of energy, fats provide about 38 kJ/g, and protein, though usually not broken down like carbohydrates and fats, can provide an additional 17 kJ/g. The total energy content in a food item is found by adding the energies from each of the componentts (carbohydrates, fats, and protein). The nutritional label of an original Krispy Kreme donut lists 32 grams of carbohydrates, 12 grams of fat and 2 grams of protein. What is the approximate energY Content, in kl. for the carbohydrates in the donut? Please type in the number only (no units), rounded to the ones place. What is the approximate energy content. in kJ. for the fat in the donut? Please type in the number only (no units), rounded to the ones place. What is the approximate energEY content. in kJ. for the protcin in the donut? Pease type in the number only (no units), rounded to the ones place. What is the total approximate energy content. in kJ. for the donut? Please type in the number only (no units). rounded to the ones place. How many food calories are contained in the donuE if 1 Food Calorie = 4.184K. Plcast type in the number only (no unitsi. rounded to the pnes place
Thermochemistry
Thermochemistry can be considered as a branch of thermodynamics that deals with the connections between warmth, work, and various types of energy, formed because of different synthetic and actual cycles. Thermochemistry describes the energy changes that occur as a result of reactions or chemical changes in a substance.
Exergonic Reaction
The term exergonic is derived from the Greek word in which ‘ergon’ means work and exergonic means ‘work outside’. Exergonic reactions releases work energy. Exergonic reactions are different from exothermic reactions, the one that releases only heat energy during the course of the reaction. So, exothermic reaction is one type of exergonic reaction. Exergonic reaction releases work energy in different forms like heat, light or sound. For example, a glow stick releases light making that an exergonic reaction and not an exothermic reaction since no heat is released. Even endothermic reactions at very high temperature are exergonic.
