In a Synthesis reaction the more complex product will be formed from the reactants Then another type of synthesis reaction is when an element and a compound combine to form a new compound If you count the atoms and numbers this will make it easier to identify the type of reaction The reactants can be elements or compounds A compound is produced from the reaction For a synthesis reaction both electrons stay with the products which give you a charged ion 1 Iron Sulfide would be 8 Fe S8 8 FeS The Iron and the sulfide are 2 elements that combine to create a compound 2 Water would be 2 H2 g O2 g 2C02 g Water is made with the two elements Hydrogen and Oxygen This reaction is exothermic and releases energy when being made 3 Ammonia would be 3 H2 g N2 g 2 NH3 g Ammonia is made up of the two elements Hydrogen and Nitrogen This compound is formed using the Haber process Which makes Fertilizers dyes explosives and more 2 Decomposition reaction 14 sentences o 



A Decomposition reaction is a single substance that has been broken down into two or more simpler substances The simpler substances can be compounds or elements The compound is broken into smaller chemical species Decomposition involves break down into smaller molecules Decomposition is the opposite of Synthesis reaction The reactants are made up of when a single reactant produces multiple products This reaction is required to have a source of energy so it can break apart the bonds of the compounds 1 Carbonic Acid is H2CO3 which is used to make soft drinks The decomposition takes place when the acid breaks down to make carbon dioxide and water The whole equation is 2H2O 2H2 02 2 Water is H2O and it breaks down to produce Oxygen and Hydrogen gases The equation is 2H20 2H2O2 3 Calcium oxide involves the decomposition of Calcium Carbonate by heating it The equation is CaCO3 s CO2 g 3 Combustion reaction 12 sentences o A combustion reaction requires Oxygen that combines with another compound to form Carbon Dioxide and water A combustion reaction will always have carbon dioxide and water The reaction has a compound that is reacted to produces a heat or new compound The reactants of a combustion reaction are always carbon dioxide and oxygen The products are always going to be carbon dioxide and water Since Oxygen is more electronegative than carbon the electrons in carbon dioxide are shared equally Combustion reactions are always exothermic 1 When you burn wood it has to have oxygen and then the heat is made 2 Burning of Coal is C 02 CO2 This produces energy in the form of heat 3 When fireworks are lit the chemicals react with the oxygen in the air to produce the heat and light made from the firework 



4 Single displacement reaction 13 sentences o A single displacement reaction is when one element is substituted for another element in a compound One of the reactants is an element and the other one is a compound The starting materials are always going to be pure elements Then once you know what element can be replaced you can find the product of the reaction 1 Potassium reacts with water Then Hydrogen and Potassium Hydroxide is set free Then this equation was made 2K 2H2O 2K0H H2 2 Zinc reacts with Sulfuric acid to release Hydrogen gas Which makes the equation Zn H2SO4 ZnSO4 H2 3 A real life example is the statue of liberty The reaction causes the Iron to convert to copper Therefore that led to the Iron begin to rust Which led to the statue of liberty being replaced later 5 Double displacement reaction 12 sentences o A double displacement reaction is when 2 ionic compounds are exchanged making 2 new compounds The reaction they have together is like swapping cations or anions but never both When the cations and anions switch between the 2 reactants they form a product The electrons are either positive ion or a negative ion There are 3 types of double displacement they are precipitation gas producing and weak electrolytes 1 Silver is traded for a nitrite ion for the sodium chloride ion The equation is AgNO3 NaCl AgCl NO3 2

A real life example would be baking cupcakes When you make cupcakes you put baking soda and then that reacts to the acidic substances Without it the reaction we wouldn't be able to make cupcakes 3 Hydrogen Chloride mixed with Sodium oxide creates table salt The equation is HCL NaOH NaCl H2O 6 Oxidation reduction reaction 14 sentences o A chemical reaction involves the transfer of electrons between 2 things You can tell if there is a transfer of electrons by the oxidation number between the product and reactant When an atom gains electrons it is reduced Then when the atom is lost its oxidized The reactants that bring oxidation are called the oxidizing agent Once the oxidation number changes from reactant you will know the product 1 Carbon dioxide is reduced to sugar and water is oxidized to oxygen The equation is 6CO2 6H2 O C6H12O6 6O2 2 When natural gas is burned that is an example of Oxidation reduction reaction Methane is oxidized to become carbon dioxide The equation is CH 4 2O2 CO2 2H2O 3 Magnesium atom is oxidized to a magnesium ion The equation Mg 2e Mg2
