Answer:
Minimizing repulsion by maximizing the bond angles
Explanation:
VSEPR is defined as 'valence shell electron pair repulsion' theory. The key principle is that repulsion of adjacent lone pairs of electrons or the electrons that are shared within a bond creates bond angles.
The bond angles are maximized in order to minimize the repulsion in the most stable geometrical shape of the molecule.
That said, in VSEPR theory we tend to achieve the greatest possible angles between the bonds and lone pair electrons in order to obtain the lowest repulsion between them.
Krypton- rare gas, element in the noble gases
Lye- sodium hydroxide, compound
Graphite- element
Vinegar- is acetic acid, compound( aqueous solution)
Answer:
"Like dissolves like" is an expression used by chemists to remember how some solvents work. It refers to "polar" and "nonpolar" solvents and solutes. Like dissolves like, that means polar dissolves polar, so water dissolves salt.
Explanation:
In some plants such as Cactuses, the stem is flattened and green and carries out the function of the leaf. Such a stem, adapted for the manufacture of food is called phylloclade. The leaves here are reduced or modified into spines to lessen the transpiring surface.
