Which of the following is an example of endothermic reaction? (2023)

Which reaction is an endothermic reaction?

Endothermic reactions are chemical reactions in which the reactants absorb heat energy from the surroundings to form products.

An endothermic reaction absorbs energy during a chemical reaction. Among the choices, baking a cake is an example of an endothermic reaction.

Option 2 is the correct answer: Decomposition reactions are always endothermic in nature. In a decomposition reaction, a chemical compound is broken into its constituent components. The process takes place through the breaking of bonds between the constituent atoms of the compound.

The chemical reaction in which the heat is absorbed is known as an Endothermic reaction. Examples are melting ice cubes and melting solid salts.

Brushing your teeth, washing your hair, and lighting your stove are all examples of exothermic reactions. Keep reading to learn about combustion, neutralization, corrosion, and water-based exothermic reactions.

Where an exothermic reaction releases heat, an endothermic reaction absorbs heat. One common endothermic reaction is ice melting.

Which event is endothermic? Iron reacts with oxygen in a chemical hand-warmer.

Which of the following is not an endothermic reaction?

Fusion.

The chemical reaction in which the heat is absorbed is known as an Endothermic reaction. Examples are melting ice cubes and melting solid salts.

Chemical reactions that absorb (or use) energy 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.

Final answer: Dilution of an acid and Reaction of water with Quicklime are exothermic processes.

Endothermic reaction. A reaction in which energy is ABSORBED by matter. Energy flows into the system from the surroundings generally in the form of heat (heat is not being released, it's being absorbed) (getting colder)

Because we must add heat, boiling water is a process that chemists call endothermic.

Combustion is a high-temperature exothermic (heat releasing) redox (oxygen adding) chemical reaction between a fuel and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke.

Fire is a chemical reaction that converts a fuel and oxygen into carbon dioxide and water. It is an exothermic reaction, in other words, one that produces heat.

Therefore, endothermic reactions absorb heat from their surroundings (e.g. ice melting and “cooling” a drink). Conversely, exothermic reactions release heat to their surroundings (e.g. burning wood in a fireplace).

Endothermic reaction. A reaction in which energy is ABSORBED by matter. Energy flows into the system from the surroundings generally in the form of heat (heat is not being released, it's being absorbed) (getting colder)

Which of the following reaction is endothermic in nature ao → O bn → N cc → c df → f?

Thus, option A and option D are correct, they are endothermic reactions.

Combustion of F2 is endothermic.

Formation of O− is exothermic, whereas formation of O2− is endothermic.

Combusting is an exothermic, chemical reaction.

Explanation: Endothermic Reaction - : The Reaction in which heat is either absorbed from surrounding and has to be supplied continuously from outside , it is called Endothermic Reaction . Exothermic reaction - : The chemical Reaction in which heat is given out called as , Exothermic Reaction .

The chemical reaction in which the heat is absorbed is known as an Endothermic reaction. Examples are melting ice cubes and melting solid salts.

The given reaction is a combination reaction because carbon and oxygen atoms are combining to form carbon dioxide molecule as a single product. It is also an exothermic reaction because heat is being released.

Thus, evaporation of water is possible through absorption of heat energy. Thus, evaporation is an endothermic process.

This is an EXOTHERMIC reaction.

H2(g) + Cl2(g)⟶ 2HCl(g) + 185 kJ . This reaction is exothermic.

Is H2 O2 H2O exothermic endothermic?

The reaction between hydrogen and oxygen is exothermic- it releases energy to the surroundings: hydrogen + oxygen → water 2H2 + O2 → 2H2O Fuel cells use the reaction between a fuel and oxygen to produce electrical energy.

The oxidation of SO2 by O2 to SO3 is an exothermic reaction according to equation 2SO2(g)+O2(g)⇌2SO3(g)+ Heat . The yield of SO3 will be maximum if. No worries!

Answer. Electron gain enthalphy for oxygen is negative because oxygen being an electronegative atom can easily accept electron. ion we supply energy in form of heat . This males it endothermic.

During this process, the change of state is from gas to liquid. Conversion of state from gas to liquid releases energy, and hence it is an exothermic reaction.
