Theoretical yield of chemical reactions Gaseous butane (CH, (CH), CH₂) reacts with gaseous oxygen gas (0₂) to produce gaseous carbon dioxide (CO₂) and gaseous water (H₂O). What is the theoretical yield of water formed from the reaction of 5.8 g of butane and 6.4 g of oxygen gas? Round your answer to 2 significant figures. 3.17-10 4 O.P 1892 Xravian V
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.
Theoretical yield: Theoretical yield is the amount of a product that results from the full conversion of the limiting reactant in a chemical reaction.
Limiting reactant: It is the reactant that gets entirely used up in the reaction and controls product formation.
Given: The mass of butane (CH3(CH2)2CH3) is 5.8 g and the mass of oxygen (O2) is 6.4 g. Butane and oxygen react to give water (H2O) and carbon dioxide (CO2).
To calculate: Theoretical yield of water.
