Describe solids,liquids, and gases interms of how they fill a container. Use your descriptions to identify the physical state (a
nadezda [96]

Explanation:

As it is known that in solids, molecules are held together because of strong intermolecular forces of attraction. As a result, they are held together and have definite shape and volume.

Whereas in liquids, molecules are not held so strongly as they are in solids. Hence, they move from their initial position and they do not have definite shape but they have definite volume.

Liquids obtain the shape of container in which they are kept.

In gases, molecules are held together by weak intermolecular forces. As a result, they move far apart from each other and occupy the space of a container or vessel in which they are placed.

The physical state (at room temperature) of the following are determined as follows:

(a)  Helium in a toy balloon : Helium at room temperature exists as a gas. So, when helium is present in a toy balloon then it acquires the volume of toy balloon.

(b)   Mercury in a thermometer : Mercury at room temperature exists as a liquid. When it is placed in a thermometer then volume of mercury does not get affected.

(c)    Soup in a bowl : Since, soup is a liquid. Hence, its volume will not change according to the volume of container.

What are the forces that hold sodium and chloride ions together?
Phantasy [73]
Sodium is a metal, Chloride is a non-metal.

Right off the bat, you know that in order for both of these atoms to achieve a full valence shell that the metal has to lose electrons, and the non-metal has to gain them.

Therefore, you have the transfer of electrons in this bond in order to form ions.
Na+ and Cl-. This transfer of electrons in a bond is called an {{ Ionic Bond}}

Geef de systematische naam van P2S3
Tresset [83]

The question is: Give the systematic name of P_{2}S_{3}.

Answer: The systematic name of P_{2}S_{3} is diphosphorus trisulfide.

Explanation:

As the chemical formula of given compound is P_{2}S_{3}. This sows that there are two phosphorus atoms so a prefix "di" will be added before the name of phosphorus atom.

Whereas there are three sulfur atoms present here. So, a prefix "tri" will be added before naming the sulfur atom. As sulfur is the anion so a suffix '-ide' will be added to its name.

Hence, name of the compound P_{2}S_{3} is diphosphorus trisulfide.

Thus, we can conclude that the systematic name of P_{2}S_{3} is diphosphorus trisulfide.
