Answer:

In FeO iron atom exist as Fe+ cation but in Fe2O3 iron atom exist as Fe3+ cation.

Explanation:

Feo=Fe+  +  O-

Fe2O3 =2Fe3+  +  3O2-

The difference in the charge of iron cation deeply affect the compound formulas because in FeO the  Fe cation has 1 unit positive charge where in Fe2O3 the  Fe cation has 3 units positive charge.

   That"s why these two chemical compounds made up of similar atoms differ in their chemical formulas.

Chlorine is found abundantly in earth crust and ocean.

Explanation:

The elements of group 17 are called halogens. These are six elements Fluorine, Chlorine, Bromine, Iodine, Astatine. Chlorine is one of them.

it is greenish-yellow irritating gas.

its melting point is 172.2 K

its boiling point is 238.6 K

It is present in earth crust and ocean abundantly.

In ocean chlorine is found in the form of salt sodium chloride.

About 1.9% mass of sea water consist of chlorine ions.

In earth crust it is present in minerals such as carnallite and sylvite.

it is disinfectant and can kill the bacteria.

it is also used in manufacturing of paper, paints and textile industries.

Ad libitum [116K]

Answer:

The reaction can produce 287 grams of iron(II) carbonate

Explanation:

To solve this question we must find the moles of iron(II) chloride that react. Using the chemical equation we can find the moles of iron(II) carbonate and its mass -Molar mass FeCO3: 115.854g/mol-

<em>Moles FeCl2:</em>

1.24L * (2.00mol / L) = 2.48 moles FeCl2

As 1 mol FeCl2 produce 1 mol FeCO3, the moles of FeCO3 = 2.48 moles

<em>Mass FeCO3:</em>

2.48mol * (115.854g / mol) =

<h3>The reaction can produce 287 grams of iron(II) carbonate</h3>
