Answer:
CH₂O
Explanation:
From the question given above, the following data were obtained:
Carbon (C) = 39.9%
Hydrogen (H) = 6.7%
Oxygen (O) = 53.4%
Empirical formula =?
The empirical formula of acetic acid can be obtained as follow:
C = 39.9%
H = 6.7%
O = 53.4%
Divide by their molar mass
C = 39.9 / 12 = 3.3
H = 6.7 / 1 = 6.7
O = 53.4 / 16 = 3.3
Divide by the smallest
C = 3.3 / 3.3 = 1
H = 6.7 / 3.3 = 2
O = 3.3 / 3.3 = 1
The empirical formula => CH₂O
Peptide bonds, hydrogen bonds, disulfide linkages, van der Waals, and electrostatic forces of attraction are the chemical bonds that stabilize the different structures in primary, secondary, tertiary, and quaternary structures.
The advanced structure of proteins gives rise to two kinds of major molecular shapes which are fibrous as well as globular structures. The main forces which are involved in stabilizing the secondary along with the tertiary structures of proteins include hydrogen bonds, disulfide type linkages, van der Waals attraction, and electrostatic forces of attraction.
The primary structure is generally determined by adjoining peptide bonds where the link is adjoining amino acids in sequential order. Tertiary structure is determined by the existence of disulfide bonds in between hydrophobic interactions as well as cysteine residues whereas the quaternary type structure is determined by multiple subunits of a protein that undergo various interactions.
Hydrogen bonds exist in a protein molecule as its large number can form between adjacent regions of the polypeptide chain in folded form and stabilize its three-dimensional kind of shape.

Both the Sun and the Earth are sources of heat that power an interconnected set of dynamic systems (lithosphere, hydrosphere & cryosphere, atmosphere, biosphere).
Within the Sun, heat is transferred by radiation and convection, which involves circulation of hydrogen ions. Within the Earth heat is transferred by conduction and convection, which involves circulation of silicates in the mantle and the crust, and by the circulation of iron in the liquid outer core. On the surface of the Earth and the atmosphere, heat emanating largely from the Sun is transferred by convection, which involving the circulation of water and carbon. Both the Sun and the Earth and their atmospheres are layered. Both systems evolve and change.
I think the answer is Fe. Hope it help!
