Write Balanced Equations and name the reaction type for the following reactions;

1) When heated, calcium carbonate decomposes to form calcium oxide and carbon
dioxide


CaCO3 → CaO + CO2
2) Barium oxide reacts with water to form barium hydroxide


BaO + H2O → Ba(OH)2
3) Zinc reacts with copper (II) nitrate to from zinc nitrate and copper.


Zn + Cu(NO3)2 → Zn(NO3)2 + Cu
4) Propane (C3H8) is burned with oxygen to produce water vapor and carbon dioxide


C3H8 + 5 O2 → 4 H2O + 3 CO2
5) When heated, calcium sulfite decomposes to form calcium oxide and sulfur dioxide.


CaSO3 → CaO + SO2
6) Iron reacts with sulfuric acid to form iron (III) sulfate and hydrogen gas.


Fe + H2SO4 → FeSO4 + H2
7) Manganese (II) iodide decomposes when exposed to light to form manganese and
iodine.


MnI2 → Mn + I2
8) Dinitrogen pentoxide reacts with water to produce nitric acid


N2O5 + H2O → 2 HNO3
9) Magnesium reacts with titanium (IV) chloride to produce magnesium chloride and
titanium


2 Mg + TiCl4 → 2 MgCl2 + Ti
10) Benzene (C6H6) is burned in oxygen to produce carbon dioxide and water vapor.


2 C6H6 + 15 O2 → 12 CO2 + 6 H2O
11) Calcium hydride reacts with water to produce calcium hydroxide and hydrogen gas.


CaH2 + 2 H2O → Ca(OH)2 + 2 H2
12) Sulfuric acid reacts with potassium hydroxide to produce potassium sulfate and
water.


H2SO4 + 2 KOH → K2SO4 + 2 H2O
