Balance the following skeleton reaction and identify the oxidizing and reducing agents: h2s(g) + no3 > ’ s8(s) + no(g) [acidic]

Balance the following skeleton reaction and identify the oxidizing and reducing agents: h2s(g) + no3 > ’ s8(s) + no(g) [acidic] include the states for each reactant and product in the balanced chemical equation. do not include the states when identifying the oxidizing and reducing agents.

Answers

Answer : Oxidizing agent is NO^-_3 and Reducing agent is H_2S

Explanation :

The given unbalanced redox reaction is,

H_2S(g)+NO^-_3(aq)rightarrow S_8(s)+NO(g)

In acidic medium, the balanced redox reaction is,

24H_2S(g)+6NO^-_3(aq)16H^+(aq)rightarrow 3S_8(s)+16NO(g)32H_2O(l)

Oxidizing agent : Oxidizing agents are those agent which oxidizes other substance and itself get reduced.

Reducing agent : Reducing agents are those agent which reduces other substance and itself get oxidized.

In this redox reaction, NO^-_3 is an oxidizing agent and H_2S is a reducing agent.

The redox reaction is also shown below.

Balance the following skeleton reaction and identify the oxidizing and reducing agents:  h2s(g) + no

C + O2 → CO2

Explanation:

C + O2 → CO2

Explanation:

C + O2 → CO (1)

from equ (1) on reactant side, C has 1 mole, O has 2 moles

from equ (1) on product side, C has 1 mole, O has 1 mole

Thus, to balance the equation, O should have 2 moles

C + O2 → CO2
