//What happens in a synthesis reaction?//
In a synthesis reaction, two or more simple substances join together to form a new compound.

//What does the generic form of a synthesis reaction look like?//
A + B → AB

//What does an sentence equation look like?//
Hydrogen combines with Oxygen to form Dihydrogen Monoxide.

//How do I change from a sentence equation to a formula?//
Lets learn how to change the following sentence equation into a formula equation:

//Hydrogen combines with Oxygen to form Dihydrogen Monoxide//

1) First, we need to know how to set up an equation. We know that on one side of an equation there are reactants, and on the other side there is the product. And we also know that the reactants, when combined, produce the product.


 * EX:** //Reactant// [produces] //Product//

2) Second, we need to figure out which substances are the reactants and what is the product of our sentence equation.

......^reactant^.......................^reactant^......................^product^
 * EX: Hydrogen** combines with **Oxygen** to form **Dihydrogen Monoxide**.

3) Now we need to know whether the sentence contains covalent or ionic substances. We know that covalent bonds are made up of two non-metals and ionic bonds are made up of one metal and one non-metal.

....^non-metal^......................^non-metal^
 * EX:** **Hydrogen** combines with **Oxygen** to form Dihydrogen Monoxide.

Non-metal + non-metal = covalent. The sentence equation above is covalent because it consists of two non-metals.

4) If the sentence equation is covalent, look at the covalent steps below. If the sentence equation is ionic, look at the ionic steps below.

__**COVALENT STEPS**__ 1) Just write what the name says


 * EX:** H + O → H2O

__**IONIC STEPS**__ 1)Write symbols 2) Figure out charges 3) "Switcheroo" 4) Reduce

5) Balance the formula equation (I will explain how to balance formulas in the next question).


 * EX:** H + **2**O → H2O

6) If you have the same polyatomic compounds on both sides, make sure you do not break it up!

//How do I balance an equation?//
1) Make a table under the equation

2) Count the number of atoms of each type.


 * EX:** H + O → H2O

Side 1: H has 1. O has 1. Side 2: H has 2. O has 1.

3) If the atoms on both sides are balanced, then stop. If not balanced you have to change the coefficient.


 * EX:** H + **2**O → H2O

4) Do not change formulas when balancing! Only change the coefficients!

H2O(water) is an example of a product from a synthesis reaction.
