Give the balanced chemical equation (including phases) that describes the combustion of butene, C4 Hs (g). Indicate the phases using abbreviation (s), (1), or (g) for solid, liquid, or gas, respectively. Express your answer as a chemical equation. • View Available Hint(s) ΑΣφ ? A chemical reaction does not occur for this question. Submit Part D When heated, solid copper(II) carbonate decomposes to solid copper(II) oxide and carbon dioxide gas. Give the balanced chemical equation (including phases) that describes this reaction. Indicate the phases using abbreviation (s), (1), or (g) for solid, liquid, or gas, respectively. Express your answer as a chemical equation.
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.
a. This question belong to hydrocarbon.
When hydrocarbon burnt in excess of oxygen produce carbon dioxide and water.
