based on their descriptions, classify these chemical changes as endothermic or exothermic.

How do you classify a reaction as endothermic or exothermic? – An exothermic process releases heat, causing the temperature of the immediate surroundings to rise. An endothermic process absorbs heat and cools the surroundings.”

How can you tell if a chemical equation is endothermic or exothermic? –

Which of the following changes are exothermic or endothermic? – Solution : (a) Decomposition of ferrous sulphate is an endothermic reaction because heat is absorbed during the reaction.
(b) The process of dissolving sulphuric acid in water (i.e., dilution of sulphuric acid ) is a highly exothermic reaction.

What are 5 examples of endothermic reactions? – Endothermic Processes Melting ice cubes. Melting solid salts. Evaporating liquid water. Converting frost to water vapor (melting, boiling, and evaporation, in general, are endothermic processes.

What are some examples of endothermic and exothermic reactions? – › chemistry › endothermic-exothermic-r…

What are exothermic and endothermic reactions explain with examples? – CaO(s) + H 2 O(l) → Ca(OH) 2 (aq) + Heat. Since heat is produced / released in this reaction, this reaction is called an exothermic reaction. A chemical reaction in which a large amount of heat / energy is absorbed is called endothermic reaction. For example, On heating of Calcium Carbonate (limestone)

What makes a chemical reaction endothermic? – Chemical reactions that absorb (or use) energy overall are called endothermic. In endothermic reactions, more energy is absorbed when the bonds in the reactants are broken than is released when new bonds are formed in the products.

What are the examples of exothermic reaction? – › iit-jee › real-life-examples-of-…

Which of the changes are exothermic? – 1—freezing, condensation, and deposition, which are the reverse of fusion, sublimation, and vaporization—are exothermic.

Which among the following is an exothermic reaction? – Explanation: When hydrogen gas reacts with oxygen gas it liberates heat energy in the form of product that means heat energy comes with steam so that the reaction between hydrogen gas and oxygen gas is called exothermic reaction.

Which among is exothermic? – Respiration is an exothermic reaction.

What is endothermic change? – Endothermic reactions are chemical reactions in which the reactants absorb heat energy from the surroundings to form products. These reactions lower the temperature of their surrounding area, thereby creating a cooling effect.

Which of the following are endothermic changes? – Fusion, vaporization, and sublimation are endothermic processes.
