Chemical reactions are responsible for life as well as all the products that we use during our lives. But there are some common misconceptions about reactions, especially that the product of a ...

Chemical reactions occur because bonds between atoms are either broken or formed. When atoms or molecules come together, they form new substances called compounds. These compounds can then undergo ...

Several factors influence the type of products formed in a chemical reaction. These include: Reactants: The nature of the reactants, their chemical properties, and their stoichiometry (the relative ...

In the reaction, the bonds in the methane and oxygen molecule come apart, the atoms rearrange and then re-bond to form water and carbon dioxide. The little number written at the lower right after an ...

Here are some practice problems to test your understanding. Predict the major product for each reaction: ...

The processes like crystallisation, boiling, vaporisation, burning of colour, melting point, hardness etc, are called physical changes. These are reversible in nature. The processes like ...

The atom economy of a chemical reaction is a measure of the percentage of reactants that become useful products. Inefficient, wasteful processes have low atom economies. Efficient processes have high ...

A new study has identified the significance of a new class of chemical reactions -- previously ignored -- involving three molecules that each participate in the breaking and forming of chemical bonds.

Melting and freezing are both physical changes, which are often easy to reverse. To reverse this process, the water would need to be cooled enough until it freezes back into ice. This works because ...
