What is the difference between the number of electrons in an atom of selenium,Se, and the number of electrons in an atom of alum
aliina [53]

Answer:

A)21

Explanation:

To know the difference between the number of electrons in the two atoms, we must first know the number of electrons in the atoms.

For Selenium, Se, we have 34 electrons. The element is in group 6 on the periodic table.

Aluminum on the other hand is in the Boron family with a total of 13 electrons.

The difference,( 34-13) electrons gives a total of 21 electrons

explain observation made when anhydrous calcium chloride and anhydrous copper (ii) sulphate are separately exposed to the atmosp
Burka [1]

Answer:

Anhydrous calcium chloride  dissolves and becomes liquid

Anhydrous copper (ii) sulphate will produce crystal particles

Explanation:

Anhydrous calcium chloride is deliquescent and hence when it is exposed to air, it absorbs water from air. After absorbing water, it dissolves and after some time a pool of clear liquid appears.

Anhydrous copper (ii) sulphate will form crystal structures  and the following reaction will takes place

CuSO4 + 5 H20 --> CuSO4.5H2O
