Air moves when the molecules are free meaning they aren't close up to each other or trying to fill up space, they are moving freely.
A mixture of oil and water is:
Heterogeneous
immiscible
<h3>What type of mixture of oil and water is?</h3>
The water molecules attract each other, and the oil molecules stick together. That causes oil and water to form two separate layers. Water molecules pack closer together, so they sink to the bottom, leaving oil sitting on top of the water. The mixture can be called as Emulsion. It is an immiscible liquid and the mixture is heterogeneous as oil floats on top of water surface but do not mix with it.
Thus, correct options are Heterogeneous and immiscible.

Film badges is a personal dosimeter used for monitoring cumulative radiation dose due to ionizing radiation.
A panel or layers of photographic film covered with black paper and exposed to air ,salt,and other chemicals on clear acetate
240 g NaOH
<em>Step 1</em>. Calculate the moles of NaOH
Moles of NaOH = 0.750 L solution × (8 mol NaOH/1 L solution) = 6 mol NaOH
Step 2. Calculate the mass of NaOH
Mass of NaOH = 6 mol NaOH × (40 g NaOH/1 mol NaOH) = 240 g NaOH
the answer is c) just took the test so these are facts.
