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 ?

C6H6
Na6Ba6
NeNa
HCl

C6H6

Explanation:

Now let us take a recap of Joelle's criteria for a wall filling material;

1) the material must be a thermal insulator

2) materials should not be acidic

3) they will not dissolve too easily in water.

If we consider the options provided, Na6Ba6  and NeNa do not exist. HCl is an acid and does not match Joelle's criteria. Hence the answer must be C6H6.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
