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.

Answer : Oxidizing agent is and Reducing agent is

Explanation :

The given unbalanced redox reaction is,

In acidic medium, the balanced redox reaction is,

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, is an oxidizing agent and is a reducing agent.

The redox reaction is also shown below.

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.  

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.
