1. In Ontario, some electricity comes from coal-burning generators. Coal is a natural form of carbon that has a large amount of sulphur mixed in with it. Here are the balanced equations for the combustion of coal and sulphur: carbon + oxygen → carbon dioxide C + O 2 → CO 2 sulphur + oxygen → sulphur dioxide S + O 2→ SO 2 Answer the following questions based on the burning of coal to produce energy: a) In what way is the combustion of sulphur harmful to the environment? b) Write the word equation and balanced chemical equation for the reaction that produces this harmful environmental effect. My Answers I am not sure how if part b) is right or how to balance it. This is the complete question. a) The combustion of sulphur produces sulphur dioxide (SO2). b) Word Equation: sulphur dioxide + water = sulphuric acid Balanced Chemical Equation: SO 2+ H 2O =H 2SO 3 =H 2SO4
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.
