The given redox reaction is a combination reaction.

Cesium combines with iodine and forms cesium iodide.

The balanced reaction is:

$2Cs\left(s\right)+2l_2\left(s\right)鈫�2CsI\left(s\right)$

The balanced redox reaction is a displacement reaction.

$2Al\left(s\right)+3MnS{O}_4\left(aq\right)鈫�A{l}_2{\left(S{O}_4\right)}_3\left(aq\right)+3Mn\left(s\right)$

The given redox reaction is a combination reaction.

Sulfur dioxide combines with oxygen and forms sulfur trioxide.

The balanced reaction is:

$2S{O}_2\left(g\right)+O_2\left(g\right)\stackrel{}{鈫�}2S{O}_3\left(g\right)$

The given redox reaction is a combustion reaction.

Combustion of butane takes place in presence of oxygen and forms carbon dioxide and water.

The balanced reaction is:

$2C_4{H}_{10}\left(g\right)+13O_2\left(g\right)\stackrel{}{鈫�}8C{O}_2\left(g\right)+10H_{2}O\left(l\right)$

The balanced equation is:

$2Al\left(s\right)+3MnS{O}_4\left(aq\right)鈫�A{l}_2{\left(S{O}_4\right)}_3\left(aq\right)+3Mn\left(s\right)$

Now, the total ionic equation is

$2Al\left(s\right)+3M{n}^{2+}\left(aq\right)+3S{O}_4^{2-}\left(aq\right)鈫�2A{l}^{3+}\left(aq\right)+3S{O}_4^{2-}\left(aq\right)+3Mn\left(s\right)$

$S{O}_4^{2-}$is the spectator ion in the total ionic equation. As you know that spectator ion is not present in the net ionic equation. Hence the net ionic equation is:

$2Al\left(s\right)+3M{n}^{2+}\left(aq\right)鈫�2A{l}^{3+}\left(aq\right)+3Mn\left(s\right)$
