Question

What are synthesis reactions?

Answer 1

Synthesis reactions, also called combination reactions, are chemical reactions in which two or more reactants produce a single product.

Explanation:

The generic equation is `"A+B"` `rarr` `"AB"`.

Examples:

Two elements: `"2Na(s)"+"Cl"_2("g")"` `rarr` `"2NaCl(s)"`

Two compounds: `"CaO(s)"+"H"_2"O(l)"` `rarr` `"Ca(OH)"_2("s)"`

A compound and an element: `"2SO"_2("g")"+O"_2("g")"` `rarr` `"2SO"_3("g")"`
