animation in bonding and breaking

The heat of reaction generally gives the change in energy in a chemical reaction. This change in energy is the difference between heat content of the reactants (H r e a c t a n t s ) and the heat content of the products (H p r o d u c t s ). It is also called enthalpy change. It is ..

Bond Energy or Bond Enthalpy - In chemical reactions the formation of a chemical bond is accompanied by the release of energy. Conversely energy has to be supplied for the breaking of a bond. Bond strengths are commonly described by their ..

It is defined as the amount of energy required to break one mole of bonds of a particular type between the atoms of a molecule in the gaseous state. It is expressed in terms of kJ mol - 1 . When a bond is formed between the atoms, energy is released and the bond..

Types of Bond Fission - Organic reactions usually involve making and breaking of covalent bonds. Fission of bonds can take place in two wa..

The C-C and C-H bonds in organic compounds are very strong. During chemical reactions, these bonds generally do not break easily. However other atoms or groups such as Cl, OH, etc., attached to the carbon atom may get replaced easily. For example, aqueous KOH reacts w..

>As a result of tetrahedral arrangement of H 2 O molecules in the solid state, the ice structure extends in three dimensions. Further the molecules of H 2 O are not packed closely as hydrogen bonds between oxygen and H atoms are longer than covalent bonds between them. This resu..

Summary - Respiration is defined as the catabolic biochemical process during which organic compounds break down in order to release energy. The organic compounds that are broken down are called the substrates. Glucose is the most common substrate. The general equation for respiration ..

The reactions between covalent compounds occur between their molecules. These involve the breaking of covalent bonds in reacting molecules and forming new covalent bonds to give molecules of the products. These reactions are quite slow because energy is required to ..
