STARTING AMOUNT + X Determine the mass in grams of CO₂ that are produced by the complete reaction of 10.49 grams of C6H12 (cyclohexane) according to the following combustion reaction: C6H12()+ 9 O₂(g)→ 6 CO₂(g) + 6 H₂O(g) ADD FACTOR 32.91 mol O₂ 0.1246 8 CO₂ 44.01 80₂ 5.486 84.16 18.02 10.49 ANSWER 32.00 mol C6H12 mol CO₂ 6 8 C6H12 1 9 RESET 2 6.022 x 1023 8 H₂O mol H₂O
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.
Calculate the number of moles for C6H12 and use mol-to-mol ratio to calculate the mass of CO2 produced.
