There are no given choices so I can't exactly give the answer. However, the idea of mixing the solute and the solvent is dissolution. The goal is to achieve maximum interaction between solute and solvent to make a uniform solution. In this case, you can form intermolecular forces between the two.

Answer:
Calcium (Ca)
Explanation:
If you look in your reference table next to each element in the top right corner it shows their charge whether it be positive, negative or zero
Properties of Protons: Positively charged particles in the nucleus (center) of an atom.
Properties of Neutrons: Neutral particles that have no electric charge in the nucleus.
Properties of Electrons: Found outside the nucleus of the Atom..
I hope this helps! :)
Answer:
Hydrogen, 0,2 mol
Explanation:
= 22, 4 l/mol
V (
) = 6,72 
= 6,72 l
V (
) = 6,72 = 6,72 l
The formula is:
n = 
n () = 6,72l /22,4 l/mol = 0,3 mol
n () = 6,72l /22,4 l/mol = 0,3 mol (the same)
But from the equation we get a proportion that 1 mol () - 3 mol ()
(we have more hydrogen than is need for the reaction)
So there is excess of
We only need 
= 0,1 mol ()
0,3 mol (hydrogen quantity we have) - 0,1 mol (hydrogen quantity we need for the reaction) = 0,2 mol (excess)
