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 inability to balance a chemical equation is a most common difficulty to students of chemistry.” The author has attempted to remedy this very common weakness, and in addition to a concise ...

Chemical Reactions: A chemical reaction is a process where the substances 8unbdergo a change in their chemical composition. The substances that enter the reaction are called reactants that are then ...

Traditionally, chemical reactions have been described as one-line "equations" in which substrates, say A and B, convert purposefully but rigidly into a desired product, say C. Naturally, it has been ...
