What is a chemical combination of two or more different elements joined?

1 Answer

A synthesis reaction would be the easiest chemical reaction to understand.

#A+ B →AB#



The synthesis of water

#2 H_2(g) + O_2(g)→ 2 H_2O(g)#

The synthesis of potassium chloride

#2 K(s) + Cl_2(g) → 2 KCl(s)#

Note: You take two elements react them together on the reactant side (left side), and you produce one compound on the product side (right side).
