Question

joelle is a manager at a construction company, and she is interested in the chemistry behind the materials they use. she has begun studying the materials used to fill walls. she knows that to keep the temperature inside a room steady the material must be a thermal insulator, and she predicts that materials should not be acidic or else they would dissolve too easily in water. which of these is a molecular ingredient that could be used in a wall-filling material ? \\(\bigcirc\\) \\(\ce{c_{27}h_{36}n_{2}o_{10}}\\) \\(\bigcirc\\) \\(\ce{na_{6}ba_{6}}\\) \\(\bigcirc\\) \\(\ce{nena}\\) \\(\bigcirc\\) \\(\ce{hcl}\\)

Explanation:

Step1: Analyze each option's validity

• For \( \ce{C_{27}H_{36}N_{2}O_{10}} \): This formula represents a molecular compound (organic, likely a complex molecule) that can act as a thermal insulator and is non - acidic (since it's an organic molecule without acidic functional groups like -COOH or -SO₃H in a way that would make it dissolve easily in water).
• For \( \ce{Na_{6}Ba_{6}} \): Sodium (Na) and Barium (Ba) are both metals. Metals do not form compounds in this way (a compound of two metals in this ratio is not a stable or common molecular material, and metals are good conductors of heat, not insulators).
• For \( \ce{NeNa} \): Neon (Ne) is a noble gas and is very unreactive. It does not form stable compounds with sodium (Na) in this way, and this is not a valid molecular material for wall - filling.
• For \( \ce{HCl} \): Hydrochloric acid (HCl) is a strong acid. It is highly soluble in water and would dissolve easily, so it cannot be used as a wall - filling material as it would not be stable.

Step2: Determine the correct option

Based on the analysis, \( \ce{C_{27}H_{36}N_{2}O_{10}} \) is the only molecular ingredient that can be used as a wall - filling material as it can be a thermal insulator and is non - acidic.

Answer:

\( \ce{C_{27}H_{36}N_{2}O_{10}} \) (the first option)
