Explanation:
Number of moles equal to the given mass divided by molar mass of the element or compound.
Mathematically, No. of moles =
The given mass is g and molar mass is 24.30 g/mol.
Therefore, calculate the number of moles as follows.
No. of moles =
=
= mol
= mol
or, = 2000 mol
Thus, we can conclude that g of Mg has 2000 moles.
Answer:
the metal loses electrons to become a positively charged cation
Explanation:
A single water molecule can form 4 Hydrogen Bonds.
A hydrogen atom that is linked to a highly electronegative atom and another highly electronegative atom that is close by interact with one another to form hydrogen bonds, which are an unique kind of attractive intermolecular interactions. This process is known as hydrogen bonding. Hydrogen, for instance, is covalently linked to the more electronegative oxygen atom in water molecules (H2O). Therefore, the dipole-dipole interactions between the hydrogen atom of one water molecule and the oxygen atom of another H2O molecule are what cause hydrogen bonding to form in water molecules.
