Write a balanced equation and indicate the reaction type

a. ammonium nitrite --> nitrogen + water
b. ammonia + oxygen --> nitrogen (II) oxide + water
c. barium chloride + sodium sulfate --> sodium chloride + barium sulfate
d. iron (III) oxide + carbon monoxide --> iron + carbon dioxide
e. magnesium hydroxide + ammonium phosphate --> magnesium phosphate + ammonia + water
f. magnesium hydroxide + phosphoric acid --> magnesium phosphate + water

a) NH4NO2 --> N2 + 2H2O decomposition
b) 2NH3 + 2O2 --> 2NO + 3H2O combustion
c) BaCl2 + Na2SO4 --> BaSO4 + 2NaCl double replacement
d) Fe2O3 + 3CO --> 2Fe + 3CO2 redox reaction
e) 3Mg(OH)2 + 2(NH4)3PO4 --> Mg3(PO4)2 + 6NH3 + 6H2O acid-base / single replacement
f) 3Mg(OH)2 + 2H3PO4 --> Mg3(PO4)2 + 6H2O neutralization

This stuff is so easy. Its honestly pathetic that you can't figure these out. Im only a first year hs chem student and I know these. Take the time to do your own homework instead of asking people online to do it and maybe you will pass the class.
