Use the iupac nomenclature rules to give the name for this compound - al2s3.

Answer : The IUPAC name of is aluminum sulfide.

Explanation :

For formation of a neutral ionic compound, the charges on cation and anion must be balanced.

The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.

Ionic compound : It is a type of compound that is made up of the ions of the two different elements in which one element is a metal and another element is a non-metal.

The nomenclature of ionic compounds is given by:

The given compound is,

Here aluminum is having an oxidation state of (+3) called as cation and sulfur is an anion with oxidation state of (-2). Thus, they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral called as aluminum sulfide.

Hence, the IUPAC name of is aluminum sulfide.

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
