<h3>Answer:</h3>

                17.25 g of Na

<h3>Explanation:</h3>

                        The balance chemical equation is as follow,

                              2 Na + 2 H₂O    →    2 NaOH + H₂

As we know that one mole of any Ideal gas at standard temperature and pressure occupies exactly 22.4 dm³ (1 L) volume.

Then, according to equation,

            22.4 L (1 mol) H₂ was produced by  =  46 g (2 mol) of Na

Then,

                     8.40 L H₂ gas will be produced by  =  X g of Na

Solving for X,

                      X =  (8.40 L × 46 g) ÷ 22.4 L

                      X =  17.25 g of Na

GuDViN [60]

The balanced net reactiion for the following half cells will be

Sn + Cr²⁺   --->  Sn²⁺  +  Cr

<h3>What are Half cells ?</h3>

A half cell is one of the two electrodes of an electrochemical cell.

An electrochemical cell comprises two half cells, where every half cell contains an electrode and an electrolyte.

A salt bridge or direct contact is needed to connect two half cells.

The balanced net reactiion for the given half cells will be

Sn + Cr²⁺   --->  Sn²⁺  +  Cr
