What is the IUPAC name for the compound FeS?

1 answer:

5 0

The correct answer is option 3. The IUPAC name is Iron(II) sulfide. It is the less stable amorphous form. When this is powdered, it is pyrophoric or it ignites spontaneously in air. It readily reacts with hydrochloric acid producing hydrogen sulfide.

Which of the following types of equations will include spectator ions

krek1111 [17]

Answer:- B) Full ionic equation

Explanations:- A molecular equation does not have ions. It is the non charge form of the elements of compounds. When we write the full or total ionic equation for the molecular equation then ions are written for the aqueous species. The ions present on both sides(reactant and product sides) in a full ionic equation are known as spectator ions or common ions. These ions are canceled to get the net ionic equation. For example, reaction of aqueous solution of silver nitrate with aqueous solution of barium chloride to form aqueous solution of barium nitrate and a precipitate of silver chloride.

Balanced molecular equation:-

$BaCl_2(aq)+2AgNO_3(aq)\rightarrow Ba(NO_3)_2(aq)+2AgCl(s)$

Full ionic equation:-

$Ba^+^2(aq)+2Cl^-(aq)+2Ag^+(aq)+2NO_3^-(aq)\rightarrow Ba^+^2(aq)+2NO_3^-(aq)+2AgCl(s)$

If we look at the above full ionic equation then barium ion and nitrate ions are the spectator ions are they are present on both sides.

So, while writing the net ionic equation, these spectator ions are canceled.

Net ionic equation:-

$2Cl^-(aq)+2Ag^+(aq)\rightarrow2AgCl(s)$

So, it is also clear from the above example that it's the full ionic equation that include spectator ions.

positive ions are smaller than the ions from which they are formed but negative ions are larger than the is from which they are

Vadim26 [7]

Positive ions are atoms that have lost an electron from its outtermost shell. It is positive because electrons are negative and the loss of something negative makes it a bit more positive.
A negative ion is larger than its original atom because it's gained an electron.

The more electrons an atomic has on its electron cloud, the bigger the atom.

Hopefully I didn't confuse you, good luck. ♡
