 Why would reactions be grouped into classes?

Not all chemical reactions fit uniquely into only one category, occasionally a reaction may fit equally into two categories. Patterns of chemical behavior will become apparent and allow you to predict the products of the reactions. <span style="font-family: 'Comic Sans MS',cursive; font-size: 120%;"> <span style="font-family: 'Comic Sans MS',cursive;">**<span style="color: rgb(255, 0, 0);">W <span style="color: rgb(0, 0, 255);">H <span style="color: rgb(0, 255, 0);">A <span style="color: rgb(255, 0, 255);">T <span style="color: rgb(0, 255, 255);">T <span style="color: rgb(255, 255, 0);">Y <span style="color: rgb(255, 0, 0);">P <span style="color: rgb(0, 0, 255);">E <span style="color: rgb(0, 255, 0);">O <span style="color: rgb(255, 0, 255);">F <span style="color: rgb(0, 255, 255);">C <span style="color: rgb(255, 255, 0);">H <span style="color: rgb(255, 0, 0);">E <span style="color: rgb(0, 0, 255);">M <span style="color: rgb(0, 255, 0);">I <span style="color: rgb(255, 0, 255);">C <span style="color: rgb(0, 255, 255);">A <span style="color: rgb(255, 255, 0);">L <span style="color: rgb(255, 0, 0);">R <span style="color: rgb(0, 0, 255);">E <span style="color: rgb(0, 255, 0);">A <span style="color: rgb(255, 0, 255);">C <span style="color: rgb(0, 255, 255);">T <span style="color: rgb(255, 255, 0);">I <span style="color: rgb(255, 0, 0);">O <span style="color: rgb(0, 0, 255);">N <span style="color: rgb(0, 255, 0);">S <span style="color: rgb(255, 0, 255);">A <span style="color: rgb(0, 255, 255);">R <span style="color: rgb(255, 255, 0);">E <span style="color: rgb(255, 0, 0);">T <span style="color: rgb(0, 0, 255);">H <span style="color: rgb(0, 255, 0);">E <span style="color: rgb(255, 0, 255);">R <span style="color: rgb(0, 255, 255);">E <span style="color: rgb(255, 255, 0);">? <span style="color: rgb(255, 0, 0);">! <span style="color: rgb(0, 0, 255);">? <span style="color: rgb(0, 255, 0);">! <span style="color: rgb(255, 0, 255);">? <span style="color: rgb(0, 255, 255);">! <span style="color: rgb(255, 255, 0);">? <span style="color: rgb(255, 0, 0);">! ** <span style="color: rgb(255, 0, 0);"> <span style="color: rgb(0, 0, 128);"> There are five different types of chemical reactions: combination or(synthesis), decomposition, single-replacement, double-replacement, and combustion. You can classify the different categories by the number of elements or if the compound has a good reaction indicator. <span style="color: rgb(0, 0, 255);">OK <span style="color: rgb(255, 0, 0);">SO <span style="color: rgb(0, 255, 255);">HOW <span style="color: rgb(255, 0, 255);">ARE <span style="color: rgb(0, 0, 255);">THEY <span style="color: rgb(0, 255, 0);">DIFFERENT ?!?! ** <span style="color: rgb(0, 255, 0);"> The chemical equation for this synthesis reaction looks like: reactant + reactant ---> product <span style="color: rgb(0, 255, 0);">In the cartoon, the skinny bird (reactant) and the worm (reactant) combine to make one product, a fat bird.
 * <span style="display: block; font-size: 110%; font-family: 'Comic Sans MS',cursive; text-align: center; color: rgb(255, 255, 0);">
 * Combination(Synthesis):** A combination reaction is a chemical change in which two or more substances react to form a single new substance.<span style="color: rgb(0, 255, 0);"> For example, simple hydrogen gas combined with simple oxygen gas can produce a more complex substance-water!

<span style="color: rgb(0, 255, 255);"><span style="color: rgb(0, 255, 255);"> <span style="color: rgb(0, 255, 255);">reactant ---> product + product <span style="color: rgb(0, 255, 255);">In this cartoon the egg (the reactant), which contained the turtle at one time, now has opened and the turtle (product) and egg shell (product) are now two separate substances. <span style="color: rgb(255, 0, 255);">
 * Decomposition**: In a decomposition reaction a more complex substance breaks down into its more simple parts. One reactant yields 2 or more products. Basically, synthesis and decomposition reactions are opposites.<span style="color: rgb(0, 255, 255);"> For example, water can be broken down into hydrogen gas and oxygen gas. The chemical equation for this decomposition reaction looks like:

reactant + reactant -> product + product
 * <span style="color: rgb(255, 0, 255);">Single-Replacement **<span style="color: rgb(255, 0, 255);">: In a single replacement reaction a single uncombined element replaces another in a compound. Two reactants yield two products. For example when zinc combines with hydrochloric acid, the zinc replaces hydrogen. The chemical equation for this single replacement reaction looks like:

<span style="color: rgb(255, 0, 255);">Notice the guy in the orange shirt steals the date of the other guy. So a part of one of the reactants trades places and is in a different place among the products.

Below is a link to a website where you can learn how to write single displacement equations, and do some practice problems yourslef!! =) []

<span style="color: rgb(0, 255, 255);">**Double-Replacement**: <span style="color: rgb(0, 255, 255);">In a double replacement reaction parts of two compounds switch places to form two new compounds. Two reactants yield two products. For example when silver nitrate combines with sodium chloride, two new compounds--silver chloride and sodium nitrate are formed because the sodium and silver switched places. The chemical equation for this double replacement reaction looks like: <span style="color: rgb(0, 255, 255);">reactant + reactant -> product + product

 * Combustion**: Is a chemical change in which an element or a compound reacts with oxygen often producing energy in the form of heat or light.

Ex: 2Mgs+O2g--->2MgUs
