Review of Ch 9 & 11 Writing and Balancing Equations

Writing Formulas Magnesium sulfide Sodium phosphate Barium hydroxide
Copper (II) nitrite Trihydrogen bromide Calcium carbonate Hexafluoride pentanitride Iron (III) sulfate MgS Na3PO4 Ba(OH)2 Cu(NO2)2 H3Br CaCO3 F6N5 Fe2(SO4)3

Naming NaClO3 Hg2Br2 K2CrO4 HClO4 SnO2 Fe(C2H3O2)3 Ca(OH)2
Sodium chlorite Mercury (I) bromide Potassium chromate Hydrogen chlorate Tin (IV) oxide Iron (III) acetate Calcium hydroxide

Balance PbO2  PbO + O2 2PbO2 2PbO + O2 Fe(OH)3  Fe2O3 + H2O
(NH4)2CO3 NH3 + H2O + CO2 NaCl + H2SO4  Na2SO4 + HCl 2PbO2 2PbO + O2 2Fe(OH)3  Fe2O3 + 3H2O (NH4)2CO3 2NH3 + H2O + CO2 2NaCl + H2SO4  Na2SO4 + 2HCl

Type? Hf + N2  Hf3N4 Mg + H2SO4  MgSO4 + H2 C2H6 + O2  CO2 + H2O
Pb(NO3)2 + NaI  PbI2 + NaNO3 Fe + O2  Fe3O4

Write a Complete Chemical Equation
1. Bubbling chlorine gas through a solution of potassium iodide give elemental iodine and a solution of potassium chloride. 2. Solid tetraphosphorus decoxide reacts with water to produce phosphoric acid.

Predict the Products C3H8 reacts with oxygen
2. Copper reacts with aqueous silver nitrate 3. Aluminum reacts with bromine 4. Lead (II) nitrate reacts with potassium iodide

Predict the Products C3H8 + 5O2  3CO2 + 4H2O
C3H8 reacts with oxygen 2. Copper (II) reacts with aqueous silver nitrate 3. Aluminum reacts with bromine 4. Lead (II) nitrate reacts with potassium iodide C3H8 + 5O2  3CO2 + 4H2O Cu + 2AgNO3  Cu(NO3)2 + 2Ag 2Al + 3Br2  2AlBr3 Pb(NO3)2 + KI  KNO3 + PbI2
