The ranking of terms importance in deciding on the true structure of a molecule:
Experimental evidence> Lewis structure> formal charge
- In describing the structure of the molecule experimental evidence is of utmost importance followed by lewis structure and then formal charge.
- Experimental evidence is an inference of a practical technique that one will conduct to determine the original arrangement of atoms in a molecule by following a set of ordered steps.
- Evidence will give the real picture regarding the structure of the molecule as no guesswork or prediction is employed.
- Whereas Lewis structures and formal charge are the theoretical concepts that will only help in predicting the structure of a molecule which can be correct, partially correct, or wrong.
So, from this, we can conclude that the ranking of terms importance in deciding on the true structure of a molecule:
Experimental evidence> Lewis structure> formal charge

Explanation:
Carbohydrates covalently linked to proteins (glycoproteins) or lipids (glycolipids) are also a part of cell membranes, and function as adhesion and address loci for cells. The Fluid Mosaic Model describes membranes as a fluid lipid bilayer with floating proteins and carbohydrates.
Answer:The number of atoms in 2.0 mole Al is A. 2.0 Al atoms. B. 3.0 x 1023 Al atoms.
Secondly, is aluminum an atom or molecule? Aluminum is the second element in the thirteenth column of the periodic table. It is classified as a post-transition metal and a "poor metal". Aluminum atoms contain 13 electrons and 13 protons. There are 3 valence electrons in the outer shell.
Answer: v2=268.047mL
Explanation:
V1/T1=v2/T2
V1=693mL
T1=45°c to convert to Kelvin 273+45=318k
V2=?
T2=-150°c to convert to Kelvin
273-150=123k
693/318=v2/123
Cross multiply
318v2=693×123
V2=85239/318
V2=268.047mL
Answer:
Loam is soil composed mostly of sand, silt, and a smaller amount of clay. By weight, its mineral composition is about 40–40–20% concentration of sand–silt–clay, respectively.
