Chemical Equations and Reactions:  Chemical Equations and Reactions The Five Types of Chemical Reactions and Other Crap Synthesis Reactions:  Synthesis Reactions Two or more substances combine to form a new compound. A + X = AX Two compounds become one. Decomposition Reactions :  Decomposition Reactions Single compound undergoes a reaction that produces two or more simpler substances. AX= A + X One compound becomes two. Single-Displacement Reactions:  Single-Displacement Reactions One element replaces a similar element in a compound. A + BX= AX + B If A has a higher position on the activity series table, then X will be attracted to A and form a new bond with A; if it is not higher, there will be no reaction and a new bond will not form. Double-Displacement Reactions:  Double-Displacement Reactions The ions of two compounds exchange places in an aqueous solution to form two new compounds. AX + BY= AY + BX Basically, the two compounds switch partners to form new compounds. The activity series is irrelevant here. Combustion:  Combustion Oxygen gas and a compound containing hydrogen and carbon react to form carbon dioxide and water. Oxides Sulfides:  Oxides Sulfides One type of synthesis reaction that can occur would be the combination of an element with oxygen to produce an oxide of the element. Most metals will form oxides when reacted with oxygen. 2Mg(s)+O2(g)2MgO(s) Burning a strip of magnesium until only a white powder is left is an example of how to form an oxide. The same goes with sulfur. When most metals react with sulfur, a sulfide will be formed. 16Rb(s)+S8(s)------8Rb2S(s) Metals with Halogens:  Metals with Halogens Ionic compounds and covalent compounds are formed when metals react with halogens. Here are three examples… 2Na(s)+Cl2(g)2NaCl(s) Mg(g)+F2(g)MgF2(s) 2Na(s)+F2(g)2NaF(s)
