(b) Write the correct formula for each of the following ions

Fluorate - FO3 -

2. Name the following compounds:-

a) BaHPO3 - Barium hydrogen phosphite

b) AgIO3 - Silver iodate

3. Balance the following equations:

i) PbCl2 + 2AgNO3 → 2AgCl + Pb(NO3)2

ii) AlCl3 + 3NH4OH → Al(OH)3 + 3NH4Cl

iii) 2FeCl3 + 3Ca(OH)2 → 3CaCl2 + 2Fe(OH)3

iv) Pb(ClO3)2 + K2SO4 → PbSO4 + 2KClO3

v) 2Na + 2HOH → 2NaOH + H2

vi) Zn + 2HCl → ZnCl2 + H2

vii) Al + 3AgCH3COO → Al(CH3COO)3 + 3Ag

viii) MgO + 2HNO3 → Mg(NO3)2 + H2O

ix) 3MnO2 → Mn3O4 + O2

2. Why is it incorrect to alter the chemical formula when balancing a chemical equation?

Altering the chemical formula changes the entire compound and thus makes the equation invalid and incorrect.

3. Write and balance equations for the following reactions:

a) zinc sulphate + barium nitrate →

ZnSO4 + Ba(NO3)2 ---> ...
