Question

question 13 (1 point)
a mixture of the unreactive noble gases argon and neon at 25.0 °c is primarily potential energy.
true
false
question 14 (1 point)
filtered water is homogeneous and a compound.
true
false
question 15 (1 point)
a filtered mixture of water and ethanol is a solution.
true
false

Explanation:

For Question 13: At 25.0 °C, noble - gas mixture has kinetic energy from molecular motion, not primarily potential energy.
For Question 14: Filtered water is homogeneous but is a compound only if pure $H_2O$, usually has dissolved substances and is a mixture.
For Question 15: Water and ethanol are miscible, a filtered mixture of them is a homogeneous mixture, i.e., a solution.

Answer:

Question 13: B. False
Question 14: B. False
Question 15: A. True
