Chapter 8 Classifying Chemical Reactions Reactant Product
2
Composition/ Synthesis Sample equation= A+ B AB N 2 + 3H 2 NH 3 Defining Features= 2 elements or compounds combine into 1 product ONLY ONE PRODUCT
3
Decomposition Sample Equation= AB A+B CaCO 3 CaO + CO 2 Defining Features= Compound breaks down into 2 or more parts ONLY ONE REACTANT
4
Replacement/ Single Displacement Sample Equations= AX + Y AY+ X or AX + B BX + A Zn + PbCl 2 Pb + ZnCl 2 Defining Feature= More active element replaces the less active one in a compound- new partner SINGLE ELEMENT ON EACH SIDE OF REACTION
5
Double Replacement Sample Equation= AX + BY AY + BX HCl + NaOH NaCl + H 2 O Defining Features= the ions switch ‘partners’ TWO COMPOUNDS ON EACH SIDE OF THE REACTION
6
Combustion Sample Equation= AB + O 2 AO + BO CH 4 + O 2 2CO 2 + 3H 2 O Defining Features= Compound burning with oxygen to produce oxides usually water and carbon dioxide OXYGEN IS A REACTANT, OXIDES FORM (WATER AND CARBON DIOXIDE)
