You will get iron sulfate and hydrogen sulfide gas (a.k.a. rotten egg gas).

FeS + H2SO4 = FeSO4 + H2S(g)

Change in Free Energy: ΔG(20C) = -66.6kJ (negative, so the reaction runs)

Change in Enthalpy: ΔH(20C) = -37.3kJ (negative, so the reaction is exothermic)

What is the empirical formula for C8H20F4
AfilCa [17]

The given formula of C_{8} H_{2} O F_{4} can be written as C_{4} H_{10}-C_{4} H_{10}-F_{4}

<u>Explanation:</u>

Empirical formula is one of the way of representing the structural arrangement of any molecule. With this formula, we can guess the nearest atom or element in a heterogeneous molecules. Mostly the empirical and molecular formula differs for organic compounds.

As in organic compounds consists of chain of carbon and hydrogen elements. So while arranging them in a relation, we should remember that carbon should contain 4 nearby atoms and hydrogen can share only one electron to its nearby atom. Thus, a carbon can have three hydrogen and one carbon as neighbouring element.

So the given formula of C_{8} H_{2} O F_{4} can be written as

C_{4} H_{10}-C_{4} H_{10}-F_{4}

Between a water molecule and an anion, like Cl-, a _____A_____ occurs between a _____B_____ of the water molecule and the anion.
AVprozaik [17]

Between a water molecule and an anion, like Cl-, a hydrogen bon occurs between hydrogen atom of the water molecule and the anion.

<h3>What is hydrogen bond?</h3>

Hydrogen bond is a weak bond between two molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in the other. Hydrogen atom in water molecule attract anion due to presence of hydrogen bond.

So we can conclude that hydrogen bond occurs between hydrogen atom of the water molecule and the anion.
