Science Assessment ~ Topics ~ Energy: Forms, Transformation, Transfer, and Conservation ~ Misconception RGM024

Energy is released when chemical bonds break (Ross, 1993; Ayyildiz & Tarhan, 2012).

Items that test for misconception RGM024 in this project (ASPECt) and key idea (Chemical energy is associated with …)
Item ID Number	Item Description	How Often the Misconception was Chosen
RG085003	During the reaction between potassium iodide and lead nitrate, energy is required to break the bonds of the reactant molecules, and energy is released when the bonds of the product molecules are formed.	57%
RG085004	During the reaction between KI and Pb(NO3)2, energy is required to break the bonds of the reactant molecules, and energy is released when the bonds of the product molecules are formed.	56%
RG213001	If the chemical energy of the products of a chemical reaction is less than the chemcial energy of the reactants, energy was released to the surroundings because the amount of energy required to break bonds of the reactant molecules is less than the amount of energy released when bonds of the product molecules are formed.	47%
RG071003	During photosynthesis, energy is required to separate atoms of the reactants. This amount of energy is greater than the amount of energy released when atoms connect to form the products.	46%
RG035003	The amount of energy required to separate atoms of the reactants in a glow stick is less than the amount of energy released when the atoms connect to form the product.	46%
RG212001	If the chemical energy of the products of a chemical reaction is greater than the chemcial energy of the reactants, energy was taken in from the surroundings because the amount of energy required to break bonds of the reactant molecules is greater than the amount of energy released when bonds of the product molecules are formed.	42%
RG034004	Energy is always required to separate atoms of reactant molecules.	36%
