Which of the following statements is/are correct?

Areal gas approaches perfect gas behaviour at high temperature and low pressure

Molecules of ideal gas possess only translational kinetic energy at all temperatures

An ideal gas would never condense into the liquid state

The average translational kinetic energy per molecule at any given temperature is independent of the type of ideal gas

`SO_(2)` dissolves in water to form sulphur acid.

`SO_(2)` acts as a bleaching agent.

`SO_(2)` has pungent odour.

`SO_(2)` acts only as oxidising agent.

Froth floatation can also be used for non sulphide ores having sulphide impurities, and the ore is recovered by using suitable activator.

In the leaching of `Ag_(2)S` with NaCN, a stream of air is also passed because of reversible nautre of reaction between `Ag_(2)S and NaCN`

In hydrometallurgy, Zn is used as an oxidizing agent in the purification of Ag from `[Ag(CN)_(2)]^(-)`

Roasting can convert sulphide into oxide or sulphate and apart of sulphide mau also act as a reducing agent
