Answer:
Lithium is a naturally occurring alkali metal, which living organisms ingest from dietary sources and which is also present in trace amounts in the human body. In much higher concentrations, lithium is effective as a medication for mania and mood swings including manic depressive disorders
Since protons are postive and neutrons are neutral. Then it is postive.

=
= 0.0147 mol
1 : 1
∴
= 0.0147 mol
Mass = Molar Mass * Mol
∴
= [(23 * 2)+(65)+(16 * 4) + (1*4)] g/mol * 0.0147 mol
= 179 g/mol * 0.0147 mol
=
2.63 g
3. There is no precipitate, precipitates are SOLID. Meaning that they are insoluble in water. NaCl in the products is aqueous, therefore it IS soluble in water. Meaning that there is no precipitate.
Answer:
The valid quantum numbers are l=0, l=-2 and l= 2.
Explanation:
Given that,
n = 3 electron shell
Suppose, the valid quantum numbers are
l = 3
m = 3
l = 0
m = –2
l = –1
m = 2
We know that,
The value of n = 3
Principle quantum number :
Then the principal quantum number is 3. Which is shows the M shell.
So, n = 3
Azimuthal quantum number :
The azimuthal quantum number is l.
Magnetic quantum number :
The magnetic quantum number is
Hence, The valid quantum numbers are l=0, l=-2 and l= 2.
