Answer: Option (3) is the correct answer.

Explanation:

A molecular compound is a compound in which atoms used to share electrons and thus results in the formation of covalent bonds.

For example, $N_{2}O_{4}$ is a covalent compound and hence, it is a molecular compound.

Whereas LiOH and NaI are ionic compounds as their atoms has transferred electrons.

Therefore, we can conclude that out of the given options, $N_{2}O_{4}$ is the formula which represents a molecular compound.

Two posssible lewis structures for the molecule ch2s are given. determine the formal charge on each atom in both structures

jok3333 [9.3K]

The formal charge on each atom can be known by counting up the number of valence electrons that is present on each atom.

<h3>What is Lewis structure?</h3>

The term Lewis structure is the representation of a compound using its symbols and showing the valence electrons as dots. This question is incomplete as the Lewis structures were not shown.

If it is shown, we can know the formal charge on each atom by counting up the number of valence electrons that is present on each atom.

There are several hazards associated with the chemicals in the qualitative analysis experiment. for each chemical, identify the

Ilia_Sergeevich [38]

You can determine the hazards of these chemicals by looking at their material data safety sheets (MSDS).

1. 0.1 M Ag⁺: Silver compounds are absorbed by skin causing bluish pigmentation. Thus, it causes staining on skin. Also, liquid vapor may be irritating to skin and also moderately toxic when ingested.

2. 0.1 M Ba²⁺: This is mildly toxic when ingested causing stomach irritation, muscle weakness, swelling of organs like brain, liver, kidney and heart.

3. 0.1 M Fe³⁺:Iron is corrosive, has irritating vapor especially to the eyes, and toxic if ingested.

4. 6 M HCl: This is a concentrated strong acid, so it is corrosive, has irritating vapors, flammable and toxic when ingested.

5. 6 M H₂SO₄: This is also a concentrated strong acid. Moreover, it is a strong oxidizing agent. So, its hazards include: corrosive, has irritating vapors, toxic when ingested and causes staining on skin.

6. 6 M HNO₃: This is a concentrated strong acid, so it is corrosive, has irritating vapors, flammable and toxic when ingested.

7. 7.5 M NH₃: This is a weak base. It is characterized for its pungent odor. This is corrosive, has irritating vapors, toxic if ingested, and flammable.
