Question 12

Metal hydroxides =>

Answer 12

produce metal oxides + water (Ca(OH)2 => CaO + H2O)

Question 13

Salts containing oxyanions =>

Answer 13

metal oxide + nonmetal oxide (ZnSO4 => ZnO + SO3)

Question 14

Metal Chlorates =>

Answer 14

Metal chloride and O2 gas (Mg(ClO3)2 => MgCl2 + O2)

Question 15

Peroxides =>

Answer 15

Metal oxide and O2 gas (H2O2 => H2O + O2)

Question 16

Combustion reaction

Answer 16

CxHyOz + O2 => CO2 + H2O

Question 17

Single Replacement (normal)

Answer 17

two cations and two anions swap places (A+BC => AC+B)

Question 18

Single Replacement (halogens)

Answer 18

the X replaces anion Y (X2+BY => BX+Y2)

Question 19

Double Replacement Reactions

Answer 19

cations of two compounds switch places. Need to produce insoluble solid, water, or pure liquid or gas in order for reaction to go. (AB+CD => AD+BC)
