1.
a. Single replacement
b. Al + Fe₂O₃ --> Al₂O₃ + Fe
c. 2Al + Fe₂O₃ --> Al₂O₃ + 2Fe

2. 
a. Double replacement
b. Pb(C₂H₃O₂)₂ + H₂S --> PbS + HC₂H₃O₂
c. Pb(C₂H₃O₂)₂ + H₂S --> PbS + 2 HC₂H₃O₂

3. 
a. Single Replacement
b. Mg + HCl --> MgCl₂ + H₂
c. Mg + 2HCl --> MgCl₂ + H₂

4. 
a. Single Replacement
b. Zn + Pb(NO₃)₂ --> Zn(NO₃)₂ + Pb
c. Zn + Pb(NO₃)₂ --> Zn(NO₃)₂ + Pb

5. 
a. Double replacement
b. AgNO₃ + NaCl --> AgCl + NaNO₃
c. AgNO₃ + NaCl --> AgCl + NaNO₃

6. 
a. Single replacement
b. K + Ba(C₂H₃O₂)₂ --> KC₂H₃O₂ + Ba
c. 2 K + Ba(C₂H₃O₂)₂ --> 2 KC₂H₃O₂ + Ba

7.
a. Double replacement
b. LiOH + Fe(NO₃)₃ --> Fe(OH)₃ + LiNO₃
c. 3 LiOH + Fe(NO₃)₃ --> Fe(OH)₃ + 3 LiNO₃

8.

Determine the hybrid orbital of this molecule.
Pavel [41]

The hybrid orbital of this molecule is sp^3. Hence, option C is correct.

<h3>What is hybridisation?</h3>

Hybridization is defined as the concept of mixing two atomic orbitals to give rise to a new type of hybridized orbitals.

In this compound, sp^3 a hybrid orbital makes I-O bonds. Due to sp^3hybridization iodate should have tetrahedral geometry but because of the presence of lone pair of electrons the shape of IO^{3-} the ion is pyramidal.

The hybrid orbital of this molecule is sp^3. Hence, option C is correct.
