The net charge on the structure as shown in the question is -1.

<h3>What is a charged specie?</h3>

We say that a specie is charged if the specie has an excess of positive or negative charge. An excess of the positive charge means that the substance is positively charged while an excess if the negative charge simply means that the object is negative charged.

When we have a chemical structure as we have seen, it is possible that the structure as we have it could have a net charge. The net charge that the structure has can be deduced by looking at the formal charges that are carried by all the atoms that we have in the system.

The charge as we can see that is on the central atom of the molecule is the -1 charge hence this is the charge that is carried overall by the molecule.

If we then look at the structure as we can see, we can see that there is a charge of negative one that is attached to the atom of chlorine as is clearly visible and obvious from the image attached to the question.

Answer The ethanol is stabilized by strong intermolecular forces between the molecules.wer:

Explanation:

During the phase change represented by the heat of fusion the temperature does not change. The molecules in the liquid state has a higher degree of freedom but are stabilized by the strong hydrogen bonding requiring a larger into of energy to separate the molecules than the heat of fusion.

How did the experiement with the iron filings and sulfur compare with the experiment in which copper sulfate pentahydrate was he

Irina-Kira [14]

Answer. Statement second and third both are correct.

Explanation: When iron(grey) reacts with sulfur(yellow) chemical change takes place in which iron sulfide is formed which black in color.

$Fe(s) + S(s)\rightarrow FeS(s)$

When we heat copper sulfate-pentahydrate(blue) ,water molecule present in its crystal will get evaporated and it will become an anhydrous copper sulfate which will be white in color.

$CuSO_{4}.5H_{2}O(s)\overset{heat}{\rightarrow} CuSO_{4}(s)+5H_2O(g)$

So, in both the reactions change in color and change in chemical arrangement has taken place.

How many miles of iron can be produced from 3.5 moles of Fe2O3 and 6.2 moles of CO

AlekseyPX

Answer:

4.13 moles of Fe.

Explanation:

Given data:

Moles of iron produced = ?

Moles of Fe₂O₃ = 3.5 mol

Moles of CO = 6.2 mol

Solution:

Chemical equation:

Fe₂O₃ + 3CO → 2Fe + 3CO₂

Now we will compare the moles of iron with CO and Fe₂O₃.

Fe₂O₃ : Fe

1 : 2

3.5 : 2/1×3.5 = 7 mol

CO : Fe

3 : 2

6.2 : 2/3×6.2 = 4.13 mol

The number of moles of iron produced by CO are less it will limiting reactant.

Thus, moles of iron formed in given reaction are 4.13 moles.

An element has an atomic number of 78. the number of protons and electrons in a neutral atom of the element would be _____.

Maurinko [17]

78 and 78. An atom of the element has 78 electrons and 78 protons.

The atomic number is 78, so the atom has 78 protons (+).

If the atom is neutral, it must contain 78 electrons (-).
