Synthesis and decomposition reactions are opposites.
Synthesis:
A + B -> C
Decomposition:
C -> A + B
They both involve three elements or compounds, one of which is a combination of the other two.
An example:
N2O5 -> NO2 + NO3 Is a decomposition reaction.
The three types of chemical reactions are: synthesis, decomposition, and replacement.
A synthesis reaction is where two (or more) chemicals or elements combine to create one new product. A decomposition reaction is the opposite meaning it is when one compound is broken down into the 2 (or more) compounds/elements it is made up of. Both of these refer to compounds, not mixtures. Mixtures cannot have synthesis or decomposition reactions. The difference between a compound and a mixture is that a compound is chemically bonded together at the atomic level while a mixture is just mixed together.
yes some chemical reactions are harmful to us. as digestion of food, photosynthesis, decomposition of organic waste are some examples of the useful chemical reactions.
Decomposition: Takes the composition of an organism when it dies and breaks it down to tiny particles of simple matter usually becoming a nutrient in the soil. Synthesis: Is combining two or more simple elements that work together to form something new.
