The IUPAC name for the compound FeS is "iron(II) sulfide." Therefore, option 3 is correct.
The IUPAC (International Union of Pure and Applied Chemistry) name is a systematic way of naming chemical compounds.
The compound FeS consists of iron (Fe) and sulfur (S) atoms. In FeS, iron has a +2 oxidation state, and sulfur has a -2 oxidation state.
According to the IUPAC nomenclature rules for naming inorganic compounds, the cation (iron) is named first, followed by the anion (sulfide).
To indicate the oxidation state of iron, the Roman numeral II is used in parentheses after the name "iron." The resulting name is "iron(II) sulfide."

Final Answer:
Kelvin Absolute Temperature:
The kelvin, symbol K, is a unit of measurement for temperature. The Kelvin scale is an absolute scale, which is defined such that 0 K is absolute zero, the lowest temperature possible on Earth.
Historically developed from the Celsius scale, the conversion is thus:
And absolute zero, 0 K = -273.15° C, the lowest temperature possible.
Knowing this, we can solve the question as:

The Kelvin temperature equal to -33℃ is 240 K.
gas ➡ solid
gas ➡ liquid
solid ➡ gas
Answers
Answer: solid ➡ gas
Explanation:
Solid state : In this state, the molecules are arranged in regular and repeating pattern. The molecules are closely packed that means they are fixed and vibrate in place but they can not move from one place to another. and thus have least kinetic energy.
For example : Copper
Liquid state : In this state, the molecules are present in random and irregular pattern. The molecules are closely packed but they can move from one place to another.. they have intermediate kinetic energy between solids and gases.
For example : water
Gaseous state : In this state, the molecules are present in irregular pattern. The molecules are not closely packed and they can move freely from one place to another and spread out. They have highest kinetic energy.
For example : Helium gas

This is because aluminium has a 3+ charge and nitrate has a 1- charge, so you need 3 of them to balance out aluminium.
Therefore, you have one ion of aluminium.

Answers
Explanation:
Since atoms of solid aluminium can are closer to each other, therefore, when heat is supplied then transfer of energy in the form of heat will be faster.
As a result, when can is warmed up then atoms of solid aluminium can will start to vibrate more because heat will decrease the force of attraction between the molecules.
Thus, atoms will start to move away from each other and hence, they will vibrate more.
Answer:
the atoms will vibrate more.
