heterogeneous mixture, because, the layers are called phases and a heterogeneous mixture has two or more phases. the oil phase is less dense then water so it floats on top, etc.
Explanation:
C. Nobel gas are very stable because in their valance shell maximum number of electrons are present
Answer:
Answer to The solid oxide of generic metal M is added to 69 mL of water and reacts to produce a Neutralization Of The Solution Required Titration With 31 ML Of 0.89 M HCl. How Many Valence Electrons Must M Have? to 69 mL of water and reacts to produce a basic solution that is 0.20 M in the resulting compound.

Answer:
Option-D : They move freely in all directions.
Explanation:
The physical properties of gases are well explained by Kinetic Molecular Theory. The key postulates of this theory are;
1) Composition: Gases are made up of small particles called molecules. The size of these molecules is very small as compared to the distance between molecules, therefore the actual volume of molecules is taken negligible as compared to volume occupied by them.
2) Intermolecular Forces: All the gas molecules present in a container behaves independently because they have no force of interactions between them Hence, the attractive forces are taken negligible or too little.
3) Energies: Gas molecules have greater kinetic energy as compared to solids and liquids. Hence, The gas molecules move randomly. They collide with each other and with the walls of the container which causes pressure.
Conclusion:
Therefore, due to large spaces, no interactions, small sizes and high energies the gas particles move freely and there position is not stationary.
