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?

C^27H^36N^2^O10

Na^6Ba^6

NeNa

HCI
