Interpretation:
The chemical equations for complete combustion of ethane, ethene and ethyne should be determined.
Concept introduction:
Chemical equation is written in such a way that the symbolic representation of reaction represents the reaction taking place in the system. The reactants are written on the left-hand side and the products are written on the right-hand side of the equation and are separated by an arrow, two or more reactants and products are separated by “+”. The reactions for those the number of atoms of each element in the reactant and in the product, side are equal, such reactions are said to be a balanced chemical equation.
Answer to Problem 97A
The chemical equations for complete combustion of ethane, ethene and ethyne are:
Explanation of Solution
An exothermic reaction that is where energy is produced in the reaction by reacting compound with oxygen which results in the formation of water and carbon dioxide is said to be combustion reaction.
The general combustion reaction for hydrocarbon is:
The molecular formula for ethane, ethene and ethyne are:
