Answer:
Choice A. Ammonium chloride.
Explanation:
Consider the bonds in each of the four compounds.
<h3>Ammonium chloride</h3>
Ammonium chloride is an ionic compound. Each
The and ions in are connected with ionic bonds.
What make special is that its cation is polyatomic. In other words, each ion contains more than one atoms. These atoms (one atom and four atoms) are connected with covalent bonds. Therefore, has both ionic and covalent bonds.
<h3>Carbon dioxide</h3>
Carbon dioxide is a covalent compound. Each molecule contains two double bonds in total. molecules have no ionic bond.
<h3>Ethyl ethanoate</h3>
The name "ethyl ethanoate" might sound like the name of a salt (think about sodium ethanoate.) However, in reality, ethyl ethanoate is an ester. The "ethyl" here refers to the part, originating from ethanol. On the other hand, "ethanoate" refers to the part, which can be obtained from ethanoic acid.
These two parts are connected with a covalent single bond. (The in ethanoic acid is connected to the in ethanol.) As a result, there's no ionic bond in ethyl ethanoate, either.
<h3>Sodium chloride</h3>
Sodium chloride is an ionic compound. Both the ion and the are monoatomic. While the and in sodium chloride are connected with ionic bonds, neither nor contains covalent bond.

hormone that causes fight or flight: adrenaline
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 <em>causes </em><span><em>staining on skin</em>.</span> Also, liquid <em>vapor may be irritating</em> to skin and also <em>moderately toxic when ingested</em>.
2. 0.1 M Ba²⁺: This is <em>mildly toxic when ingested</em> causing stomach irritation, muscle weakness, swelling of organs like brain, liver, kidney and heart.
3. 0.1 M Fe³⁺:Iron is <em>corrosive, has irritating vapor especially to the eyes, and toxic if ingested</em>.
4. 6 M HCl: This is a concentrated strong acid, so it is <em>corrosive, has irritating vapors, flammable and toxic when ingested</em>.
5. 6 M H₂SO₄: This is also a concentrated strong acid. Moreover, it is a strong oxidizing agent. So, its hazards include: <span><em>corrosive, has irritating vapors, toxic when ingested and causes staining on skin</em>.
</span>6. 6 M HNO₃: This is a concentrated strong acid, so it is <em>corrosive, has irritating vapors, flammable and toxic when ingested</em>.
7. 7.5 M NH₃: This is a weak base. It is characterized for its pungent odor. This is <em>corrosive, has irritating vapors, toxic if ingested, and flammable</em>.
