About this document
Grade 9 Chemical Energetics Notes by gaminglegand2000 is a document available to read on EtoBox.
This document discusses chemical energetics and classifies chemical reactions as either exothermic or endothermic. Exothermic reactions release energy to the surroundings, resulting in a negative enthalpy change (ΔH). Examples include combustion, respiration, hydration, and neutralization reactions. Endothermic reactions absorb energy from the surroundings, resulting in a positive enthalpy change. Examples are thermal decomposition, photosynthesis, and dissolving ionic compounds. Energy level diagrams are u
