Presentation transcript:

Synthesis Reactions ONE PRODUCT 2 elements  one compound Or…2 compounds  one compound CaO + H 2 O  Ca(OH) 2 SO 3 + H 2 O  H 2 SO 4

Decompositions One reactant One compound  2 elements Or…one compound  2 compounds CaCO 3  CaO + CO 2

Combustion Complete combustion ___ + O 2  CO 2 + H 2 O Incomplete combustion ___+ O 2  CO + H 2 O Combustion of hydrogen 2H 2 + 2O 2  2H 2 O

Single Replacement 1 element + 1 ionic compound Metal + Ionic compound…use activity series chart… 2Na + MgCl 2  2NaCl + Mg

Halogen Single Replacement One element and one ionic compound. Same as metal SR but 2 halogens F 2 + NaCl  NaF + Cl 2 Use the halogen group for an activity series.

Double Replacement 2 ionic compounds or 1 ionic cmpd + HOH Draw a line after the first element in each and swap…RE-CRISS CROSS THE PRODUCT!
