A synthesis reaction is a type of reaction in which multiple reactants combine to form a single product. Synthesis reactions release energy in the form of heat and light, so they are exothermic.
An example of a synthesis reaction is the formation of water from hydrogen and oxygen.
In the simplest synthesis reactions, two elements combine to form a binary compound (a compound made of two elements). The combination of iron and sulfur to form iron (II) sulfide is an example of a synthesis reaction:
8 Fe + S8 → 8 FeS
Direct combination reactions aren't always just simple elements reacting to form compounds. Another everyday example of a synthesis reaction is the reaction that forms hydrogen sulfate, a component of acid rain. Here, the sulfur oxide compound reacts with water to form a single product:
SO3 (g) + H2O (l) → H2SO4 (aq)
For example, the combination of two reactants, iron and oxygen, will produce the binary compound iron oxide, commonly known as rust.
If you don’t know chemistry
Here’s some on reactions
It may not be much
But it’s still a good fraction
I don’t know where to start
So I’ll begin with this
An element plus element yield compound is synthesis
Decomposition is multiple products from a single reactant
Usually formed when energy attacks it
“It” is a compound, just to get it out
It can be replaced, what is that about
It’s about single or double, which are replacements
Any real scientist would concur to this statement
Because of the complexity, my favorite replacement is single
It’s really easy, if you and chemistry can mingle
One more reaction, so lets take a turn
If oxygen is a reactant, you may have a burn
Combustion is the name
Common examples of synthesis reactions are when a metal or non-metal reacts with oxygen to form an oxide. Synthesis reactions can also occur when a metal or non-metal combine to form a binary (2 elements)compound.
3 Fe (s) + O2 (g) → Fe2O3 (s)
2 K (s) + Cl2 → 2 KCl (s)
