Answer 1

There are no particular number of formulae, but you need to be aware of the basic symbols and valencies

Answer 2

Here are the reaction from the chapter chemical reaction and equation:

#Magnesium + Oxygen → Magnesium oxide
           Mg + O₂ → MgO

# Zinc + Sulphuric acid → Zinc sulphate + Hydrogen
        Zn + H₂SO₄ → ZnSO₄ + H2

# Fe + H2O → Fe3O4 + H2

# CO(g) + 2H₂ →→CH₃OH

# 6CO₂ +12H₂O→C₆H₁₂O₆ + 6O₂ + 6H₂O

# CaO(s) + H₂O → Ca(OH)₂

# C(s) + O2(g) → CO2

# CH₄ (g) + 2O₂ (g) → CO₂ (g) + 2H₂O

# 2AgCl --sunlight--> 2Ag +Cl₂

# Zn(s) + CuSO4(aq)→ ZnSO4(aq) + Cu

#HNO3 +Ca(OH)2 → Ca(NO3)2 + H2O

# NaOH + H2SO4 → Na2SO4 + H2O

# NaCl + AgNO3 → AgCl + NaNO3

# BaCl₂ + H₂SO₄ → BaSO₄ + HCl
