TYPES OF CHEMICAL REACTIONS

There are FIVE main types of chemical reactions v. Synthesis Reaction v. Decomposition Reaction v. Single Replacement Reaction v. Double Replacement Reaction v. Combustion Reaction

Synthesis Reactions Two reactants combine to form ONE product v“Addition” reaction General format: A + B AB EX: Al + O 2 Na + Cl 2 Al 2 O 3 Na. Cl

Decomposition Reactions ONE reactant breaks down into two or more products v. Opposite of synthesis General Format: AB A + B EX: KCl. O 3 Mg. O KCl + O 2 Mg + O 2

Single Replacement Reactions One ELEMENT replaces another element in a compound General Format: A + BC AC + B EX: Ca + Ag(NO 3) Fe + Cu. Cl 2 Ag + Ca(NO 3)2 Fe. Cl 2 + Cu

Double Replacement Reactions TWO compounds produce two NEW COMPOUNDS D The positive ions replace each other General Format: AB + CD AD + CB EX: Na. Cl + KBr K(OH) + Pb(NO 3)2 H 3(PO 4) + K(OH) Na. Br + KCl K(NO 3) + Pb(OH)2 K 3(PO 4) + H 2 O

Combustion Reactions A HYDROCARBON (contains hydrogen and carbon and sometimes oxygen) combines with OXYGEN to form CARBON DIOXIDE and WATER C XH Y General Format: + O 2 CO 2 + H 2 O EX: CH 4 + O 2 CO 2 + H 2 O

Your Turn!! Ca + O 2 2 Ca. O Br 2 + Al + Li. I synthesis Li. Br + I 2 Fe(NO 3)2 single replacement Al(NO 3)3 + Fe single replacement Mg. O + HCl Mg. Cl 2 + H 2 O double replacement C 4 H 10 + O 2 CO 2 + H 2 O combustion

Your Turn!! H 2 O 2 H 2 O + O 2 decomposition (NH 4)3(PO 4) + Sr(OH)2 Sr 3(PO 4)2 + (NH 4)(OH) double replacement H 2(SO 4) + Na(OH) Na 2(SO 4) + H 2 O double replacement Zn + Ag(NO 3) Zn(NO 3)2 + Ag single replacement Cu(NO 3) + KCl K(NO 3) + Cu. Cl double replacement
