Types of Reactions Synthesis Decomposition Single Replacement Double Replacement Combustion
Synthesis Two or more substances combine to make a more complex substance A + X ----- AX
Decomposition A compound breaks down into simpler substances. AX---- A + X
Single Replacement When 1 element replaces another element in a compound. AX + B ---- AB + X or A + XB ---- AX + B
Double Replacement When 2 different atoms in 2 different compounds trade places. AX + BY ----- AY + BX
Combustion where a compound and an oxidant is reacted to produce heat, water and sometimes a new product. CH 4 + 2 O 2 CO 2 + 2 H 2 O + heat
Solve the sample problems Zn + HCl-- ZnCl 2 + H 2 CaCo 3 -- CaO + CO 2 Au + O 2 -- Au 2 O 3 Pb(NO 3 ) 2 + KI ---- PbI 2 + KNO 3 MgCO 3 + HCl - MgCl 2 + H 2 O + CO 2
