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 \( \ce{Na_6Ba_6} \) and \( \ce{NeNa} \): These formulas do not follow standard chemical bonding rules (noble gases like Ne don't typically form such compounds with Na/Ba in these ratios, and the formulas are inconsistent with known ionic or molecular structures).
• For \( \ce{HCl} \): HCl is an acid (hydrochloric acid), and the problem states the material should not be acidic (as acidic materials dissolve easily in water), so HCl is invalid.
• For \( \ce{C_{27}H_{36}N_2O_{10}} \): This is a covalent molecular formula (organic - like, with C, H, N, O), and it's not an acid. It could potentially be a component of a thermal insulating wall - filling material.

Answer:

\( \ce{C_{27}H_{36}N_2O_{10}} \)
