synthesis;+Z.+Shea-Hill

2 atoms/compounds make 1 compound. The generic form of a synthesis is A+B->AB. An example of a synthesis reaction is hydrogen + oxygen = water. converting this into an equation, H2 represents hydrogen and O2 represents oxygen, following your reactants should be an arrow pointing right. Water (H2O) is the product (so after you make the arrow, you put the product(s) to the right of it). Water is H2O because the charge of oxygen is -2, after you do the 'switcheroo' you have two hydrogen atoms. Your equation is H2+O2->H2O. if you want to balance the equation=2 **__H__** 2 2 **__O__** 1 H2+O2->H2O you see the oxygen in the product isnt equal to the reactant. You must use a coefficient to double the O 2 **__H__** 4 2 **__O__** 2 H2+O2->2(H2O)

Now double the H on the reactant side with a coefficient. 4 **__H__** 4 2 **__O__** 2 2(H2)+O2->2(H2O)
