Clinical studies reveal that diabetic patients who are non-dependent on insulin have improved metabolic control when placed on a high-fructose, low-glucose diet. The complete oxidation of D-fructose, C5H1005, involves: C5H1005(s) + 5 O2(g) 5 CO2(g) + 5 H₂O (1) Consider the following molar masses: C5H1005 (150.1 g/mol), O2 (32.00 g/mol), CO₂ (44.01 g/mol), H₂O (18.02) Instructions: Fill in the blanks by writing only the numerical value, in correct significant figures, without the units. 1. The complete oxidation of 0.30 mole of D-fructose requires 2. To completely convert 5.0 molecules of D-fructose into carbon dioxide and water, are needed. 3. moles of O₂. 4. molecules of oxygen gas micrograms of O₂ is needed to completely oxidize a quadrillion (i.e. 1015) molecules of D-fructose? Express your answer in 1 significant figure Recall 1 g = 106 µg grams of oxygen gas is needed to convert 3.0 g of D-fructose into carbon dioxide and water.
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.
