storchak [24]2 years ago
4 0

Answer:

3AlCl₃

Explanation:

molar mass of aluminum chloride AlCl₃ is 133.33 g/mole

133.33 times 3 is 400

put 3 in front of AlCl₃

3AlCl₃

the elements fluorine,chlorine,bromine,and iodine are all found in the same group on the table. these elements are grouped toget
madreJ [45]

Answer:

Fluorine, chlorine, bromine and iodine are grouped together because they have the same number of valence electrons.

Explanation:

Fluorine, chlorine, bromine and iodine are all found in group 7, which is the second-last column from the right. Group 7 elements are also called the "Halogens" family.

The group number also tells you the number of valence electrons that the elements have in that group. Valence electrons mean the outermost electrons (See picture).

For example, fluorine has two shells (the circles with dots on them). The outermost electrons, or valence electrons, are the dots on the biggest circle. There are 7 dots, so there are 7 valence electrons, which corresponds with Group "7".

A full shell (except the for first shell) is when there are 8 dots. Since 7 is so close to 8, Halogens are very reactive.

Fluorine, chlorine, bromine and iodine all have 7 valence electrons and are in the Halogens family, which are very reactive.

If crystal growth does not start on its own after the solution in the flask returns to room temperature, identify the best ways
deff fn [24]

Answer: The best way to promote the process are:

--> Add a bit of solid as a seed crystal.

--> Scratch the bottom of the flask gently with a stirring rod.

Explanation:

A crystal growth is seen is SUPERSATURATED solutions which contains more solute than it can normally dissolve at that given temperature. It is usually very UNSTABLE and capable of releasing the excess solute if disturbed, either by shaking or seeding with a tiny crystals.

Crystallization can be used for the separation of two salts with different solubilities as well as for purification of a soluble salt that contains insoluble solid impurities. Recrystallization improves the validity of the process. Crystallization can be initiated by:

--> Scratching the bottom of the flask gently with a stirring rod: scratching initiates crystallization by providing energy from the high-frequency vibrations.

--> Adding a bit of solid as a seed crystal: Seed crystals create a nucleation site where crystals can begin growth.

How tungsten conducts electricity
Elis [28]

Answer:

Yes

Explanation:

The virtue that tungsten is metal it means that it does conduct electricity. Tungsten does conduct electricity currents quite well, such as when compared to iron and nickel. It is, however, not a good conductor as compared to other metals though it does get the job done.
