 decomposition and melting

Alex Ar [27]3 years ago

Answer:

Decomposition and melting

Explanation:

Decomposition is the process of splitting two or more compounds apart from each other. Usually, the decomposed substance have different chemicals identities hence the reason why it is a chemical process since it causes chemical change. Example is the decomposition of hydrated salts of metals. CuSO4.5H20 is a penta-hydrate salt I.e contains 5 molecules of water. If this compound is heated, two different compounds are formed and changes the chemical identity of the compound. Melting is a process of liquidizing compounds or elements to the point it changes physical state from solid-liquid. Melting does not change the chemical identity of the compound but rather the physical state of the compound.
