Not much of it we can use
Explanation:
3 percent of earth's surface water is fresh water and furthermore, 2.6 percent of this fresh water humans do not have access to.
Answer:
The versions of an element with different neutrons have different masses and are called isotopes. The average atomic mass for an element is calculated by summing the masses of the element's isotopes, each multiplied by its natural abundance on Earth.
Explanation:
8. it is simple math. 17/2 is 8.5 but you cant have half a smore im pretty sure and it is the lowest number possible
Explanation:
Polarity is defined as the development of partial charges on the atoms of a molecule. In a water molecule, there are hydrogen and oxygen atoms.
Due to the difference in electronegativity of both hydrogen and oxygen atom there is development of partial positive charge on hydrogen atom and a partial negative charge on oxygen atom.
Dipole-dipole interactions are defined as the interactions that occur when partial positive charge on an atom is attracted by partial negative charge on another atom.
So, when is attracted towards then this attraction is due to dipole-dipole interaction taking place between the sodium ion and water molecules.
Thus, we can conclude that when NaCl dissolves in water, aqueous and ions result. The force of attraction that exists between and is called a dipole-dipole interaction.
