The questions based on the given figure are to be answered. Concept introduction: Every chemical reaction follows the fundamental law of conservation of mass. According to this law the number of moles of the individual atoms on both the reactants and the products side should be same. This quantitative relationship between the reactants and the products involved in the chemical reaction is known as the stoichiometry of the reaction. The standard heat of reaction is defined as the enthalpy change during the transformation of matter in a specific chemical reaction. In such type of reactions all the reactants and the products should be in their standard state. It is denoted by the symbol Δ H reaction ° . To determine: The balanced equation for the process given figure.
