STARTING AMOUNT X Determine the mass in grams of CO, that are produced by the complete reaction of 0.05090 moles of C,H, (toluene) according to the following combustion reaction: ADD FACTOR g CO₂ x( ) 18.02 6.022 x 1023 C₂H₂(1)+ 9 O₂(g) → 7 CO₂(g) + 4H₂O(g) 92.14 g C,H, 0.02908 32.00 1 3.920 mol CO₂ 44.01 g 0₂ 4 0.08908 ANSWER g H₂O 15.68 0.3563 9 0.05090 mol O₂ 2.240 RESET 5 308.1 mol H₂O 7 mol C,H,
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.
This question belongs to Mole concept.
