Explanation :
Extraction : It is a separation technique in which one compound is separated from a mixture of compounds.
In a chemical process, the solution may not contain only the desired product but there maybe a mixture of products present.
So, for obtaining the desired product we need to get rid of the other products in a mixture like catalyst (if used), other by products or unreacted starting material.
For a compound to be extracted it has to be soluble in the extracting solvent.
Therefore, this process is based on the miscibility of solute and solvent in a mixture.
Answer:
a. H20,because it experiences hydrogen bonding.
Where is the work (I'll edit the answer)
Explanation:
Hey there!!
We generally use s,p,d,f formula.
So, let's do with it.
1.Neon
Atomic no. = 10
So, Its electronic configuration is;

2.Zinc.
Atomic no. = 30
So, it's electronic configuration is;

3. Tungsten.
Atomic no. = 74.
So, it's electronic configuration is;

4. Magnesium.
Atomic no. = 12
So, the electronic configuration is ;

Answer:
1.1 g Na2SO4
Explanation:
First convert mL to L. Then multiply by the Molarity to get moles, then multiply by the molar mass to get grams.
15 mL x 1 L x 0.50 mol Na2SO4 x 142 g = 1.1 g
10^3 mL 1 L mol Na2SO4
