Need a. s.a. p. describe the redox reaction. check all that apply. 2na(s) + cl2(g) → 2nacl(s) -sodium atoms are oxidized. -chlorine atoms lose electrons. -chlorine is the reducing agent. -sodium transfers electrons to chlorine. -sodium chloride is the oxidizing agent.

A redox (reduction-oxidation) reaction is a chemical reaction which involves loss or gain i.e transfer of electrons between two interacting systems.

The atom which loses electrons is said to have undergone oxidation and is termed as a reducing agent.

While the corresponding atom which gains electron undergoes reduction and is termed as an oxidising agent.

In this case we have:

2Na(s) + Cl2(g) → 2NaCl(s)

Here: The oxidation state of Na changes from 0 to +1

The oxidation state of Cl changes from 0 to -1

Thus, Na atoms loses electron and get oxidized

Cl atoms gain electron and get reduced.

The correct options are:

-Sodium atoms are oxidized

-Sodium transfers electrons to chlorine

answer : (a) volume of the gas = 8.67 ×   l

                (b) second virial coefficient b = -1.21226 l/mole

solution :   given,     t = 300k

                                p = 20atm

                                z = 0.86

                                n = 8.2 mmoles = 8.2 × moles

                                r =   0.082 l atm/k/mol

        find,     (a) volume of gas   and (b) second virial coefficient b at 300k.

formula used :            

                          and            

(a)            

                    = \times 0.082\times 300}{20}[/tex]

                    = 8.67 ×   l

(b)      

                    = (0.00867-1) × 8.659

                    = - 8.5839 l/mole
