A mixture of 24.95g ethene (C2H4) gas and 3.25 g of oxygen gas is ignited (assume temperature and pressure remain constant throughout the reaction).Write the balanced chemical equation, including states of matter:What is the volume in mL of carbon dioxide formed? (density of CO2 = 1.98 g/mL)What is your limiting reactant? What is your excess reactantHow much of your excess reactant remains at the end of the reaction?1.00 mL of CO2 is recovered from this reaction. What is the % yield?
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.
