Chemistry

Only 1° amine react with benzene sulphonyl chloride to give a compound which is soluble in alkali

Iron (III) iodide (FeI? ) does not exist because it is unstable. The Fe³? ion is a strong enough oxidizing agent to be easily reduced to Fe²? by the I? ion, which in turn is oxidized.

Oxygen gas (O? ) is not considered a greenhouse gas.

Metal sulphide sols are negatively charged while metal oxide sols are positively charged sols. So, CdS is negative while TiO? is positively charged sol.

In sodium hydride (NaH), hydrogen has an oxidation state of -1. In this state, it can only act as a reducing agent.

Colloidal particles are small enough to pass through an ordinary filter but can be stopped by an ultrafilter paper due to their specific particle size range.

The atomic numbers and classifications for the given elements are: As (Arsenic, atomic no. 33) is a metalloid, I (Iodine, atomic no. 53) is a non-metal, and Bi (Bismuth, atomic no. 83) is a metal.

In the ammonolysis reaction, HCl is produced as a byproduct. To neutralize this acidic impurity, the mixture is treated with NaOH.

First ionization enthaly of Mg is smaller than Ar and Cl but higher than Na.
