Exothermic chemical reactions are reactions that release heat energy to the surroundings as they occur. In these reactions, the total energy of the products is lower than the total energy of the reactants. This excess energy is released in the form of heat.

Exothermic chemical reactions are reactions that release heat energy to the surroundings as they occur. In these reactions, the total energy of the products is lower than the total energy of the reactants. This excess energy is released in the form of heat. Exothermic reactions typically involve breaking chemical bonds in the reactants and forming new bonds in the products, and the energy released in forming the new bonds exceeds the energy required to break the old bonds.
Examples of exothermic reactions include combustion reactions, such as the burning of fuels like wood, coal, or gasoline, where heat and light are produced, and neutralization reactions, such as the reaction between an acid and a base to form water and a salt, where heat is also generated. These reactions are often used in various industrial processes and have wide-ranging applications in everyday life.
An example of an exothermic combination reaction is the formation of water from its elements hydrogen and oxygen: 2H₂(g) + O₂(g) → 2H₂O(l) In this reaction, hydrogen and oxygen molecules combine to form water molecules, releasing heat energy to the surroundings. The formation of new bonds in water rRead more
An example of an exothermic combination reaction is the formation of water from its elements hydrogen and oxygen:
2H₂(g) + O₂(g) → 2H₂O(l)
In this reaction, hydrogen and oxygen molecules combine to form water molecules, releasing heat energy to the surroundings. The formation of new bonds in water releases more energy than is required to break the bonds in hydrogen and oxygen, resulting in an exothermic process.
The release of heat in an exothermic reaction elevates the temperature of the reaction mixture. This temperature rise accelerates reaction rates by increasing molecular kinetic energy. In reversible reactions, the equilibrium may shift towards the reactants due to temperature increase. UncontrolledRead more
The release of heat in an exothermic reaction elevates the temperature of the reaction mixture. This temperature rise accelerates reaction rates by increasing molecular kinetic energy. In reversible reactions, the equilibrium may shift towards the reactants due to temperature increase. Uncontrolled heat release can lead to runaway reactions, emphasizing the importance of managing heat effects in chemical processes for safety and efficiency.
Combination reactions, also known as synthesis reactions, are chemical reactions where two or more reactants combine to form a single product. In these reactions, the reactants may be elements or compounds, and they come together to form a new compound. Combination reactions are characterized by theRead more
Combination reactions, also known as synthesis reactions, are chemical reactions where two or more reactants combine to form a single product. In these reactions, the reactants may be elements or compounds, and they come together to form a new compound. Combination reactions are characterized by the absence of separate products and the formation of only one product. They are often represented by the general equation:
A + B → AB
Where A and B are the reactants, and AB is the product. Combination reactions are fundamental in chemistry and occur in various natural and synthetic processes.
When slaked lime (calcium hydroxide, Ca(OH)2) reacts with carbon dioxide (CO2) in the air, it undergoes a chemical reaction called carbonation or carbonation reaction. The reaction can be represented as follows: Ca(OH)2 + CO2 → CaCO3 + H2O In this reaction, calcium hydroxide reacts with carbon dioxiRead more
When slaked lime (calcium hydroxide, Ca(OH)2) reacts with carbon dioxide (CO2) in the air, it undergoes a chemical reaction called carbonation or carbonation reaction. The reaction can be represented as follows:
Ca(OH)2 + CO2 → CaCO3 + H2O
In this reaction, calcium hydroxide reacts with carbon dioxide to form calcium carbonate (CaCO3) and water (H2O). This process is commonly observed when slaked lime, such as that used in construction materials like mortar and plaster, reacts with carbon dioxide present in the atmosphere, leading to the formation of calcium carbonate, which can result in the hardening and strengthening of the material over time.
