Which type of crystal is typified by a sea of delocalized electronssurrounding the lattice?
O A. lonic
B. Metallic
OC. Macromolecular
D. Chemical
Reset Selection

Answers

The correct answer is option B. Metallic.

What explains the structure of metals and delocalized electrons?

Metal is composed of a huge structure of atoms arranged in a regular pattern. Electrons from the outer shell of a metal atom are delocalized and can move freely throughout the structure. This sharing of delocalized electrons results in strong metal bonds.

Metallic bonds are electrostatic attraction between metal cations and the negatively charged ocean of delocalized electrons. The sea of ​​delocalized electrons contains only valence electrons, not core electrons.

How can understanding change of state help you to seprate a salt water solution

Answers

Answer: You can apply the fact that water changes from liquid to gas when heated to its boiling point.

Explanation:

Salt solution contains salt dissolved in water. The water can be separated from the salt by evaporation of the solution to dryness. This exploits the fact that water changes from liquid to gas at it's boiling point. This is an example of change of state. When heated strongly, all the water present will be converted to vapour and the solid salt reappears.
Because if you wanted to separate the salt from the solution, you will have to know the boiling point of the water. Since one way is to evaporate water from salt, which means you boil the water and leave all the salt behind, you have a solid left, which is the salt. You had to know that water can be evaporated because it is a liquid.

The three states of matter are:
-Solid
-Liquid
-Gas

A. three beams are all lined up
B. balance tips back to the right
C. object does not slide off the pan
D. pointer lines up with the white line labeled 0

Answers

Answer:

C. object does not slide off the pan

Explanation:

Triple beam balance is the name given to an instrument that is capable of measuring the mass of objects and measuring substances. This instrument is composed of three bundles, as the name says, the front bundle, the middle bundle and the long bundle. These three beams together indicate the difference in people and measurements of the objects in individual analyzes. When the balance of the triple beam is level you will notice that the measured object will not slide out of the pan

Answer:

C: object does not slide off the pan
