Mg+Cl2--> MgCl2
Magnesium plus chlorine equals magnesium chloride
4, 2, 1, and 3 is the answer
Answer:
NaCl.
Explanation:
In the solution, ZnSe ionizes to
and
. Following reaction represents the ionization of ZnSe in solution -
⇄ 
As we want to increase the solubility of ZnSe, we must decrease the concentration of dissociated ions so that the reaction continues to forward direction.
If we add NaCl to this solution, then we have
and
in the solution which will be formed by the ionization of NaCl.
Now,
in the solution will react with two
ions to form
as follows -
⇄ 
Due to this reaction the concentration of
will decrease in the solution and more ZnSe can be soluble in the solution.
B A C ( Blood Alcohol Content ) of 0.10 means that there are 0.10 g of alcohol for every dl of blood.
5 L = 50 dl
50 * 0.10 g = 5 g
In his blood is circulating 5 grams of alcohol.
