The overall attraction of this process is called hydrogen bonding in water which have very powerful bonds. These powerful bonds are known as covalent bonds and are formed when electrons are shared by atoms.
The sharing of these electrons occur when hydrogen atoms share an electron + an oxygen atom. I hope I was able to satisfyingly answer your question. If you have any more questionings based on the information, let me know! :)

Answer:
Explanation:
A supersaturated solution is unstable—it contains more solute (in this case, sugar) than can stay in solution—so as the temperature decreases, the sugar comes out of the solution, forming crystals. The lower the temperature, the more molecules join the sugar crystals, and that is how rock candy is created.
Answer: 109.5g
Explanation:
Mg + 2HCl —> MgCl2 + H2
From the equation,
1mole of Mg required 2moles of HCl
Therefore 1.5moles of Mg will require = 1.5 x 2 = 3 moles of HCl.
Molar Mass of HCl = 1+35.5 =36.5g/mol
Mass conc. Of HCl = 3 x 36.5 = 109.5g
