Secondary structure is provided by hydrogen bonds between atoms in the polypeptide backbone of proteins. Interactions between the side chain atoms of the amino acid subunits form the conformation.
The secondary structure consists of local packing of the polypeptide chain into α-helices and β-sheets by hydrogen bonding between the peptide bond and the central carbon backbone. Tertiary (3D) structure is the shape that results from secondary structural folding determined by interactions between amino acid side chains.
Secondary structure results from hydrogen bonds that form between atoms in the polypeptide backbone. A hydrogen bond is formed between a partially negative oxygen atom and a partially positive nitrogen atom.
The tertiary structure is stabilized by side chain functional groups including several interactions, especially hydrogen bonds, salt bridges, covalent disulfide bonds, and hydrophobic interactions.

Answer:
3'008,757.5 Joules
Explanation:
First, calculate the hexane (Hx) moles:
Then, multiply the number of moles by the enthalpy of reaction (the enthalpy of reaction is given by mole of reactant):
Change to Joules:
It has negative sign due to its released energy, so the answer should be positive: 3'008,757.5 J
Answer : The resonance structure of is shown below.
Explanation :
Resonance structure : It is defined as when more than one Lewis structure can be drawn, the molecule or ion is said to have resonance.
Resonance is the concept where electrons (bonds) are delocalized over three or more atoms which cannot be depicted with one simple Lewis structure.
First we have to draw Lewis-dot structure.
Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.
In the Lewis-dot structure the valance electrons are shown by 'dot'.
The given molecule is,
As we know that sulfur has '6' valence electrons, carbon has '6' valence electrons and nitrogen has '5' valence electron.
Therefore, the total number of valence electrons in = 6 + 4 + 5 = 15
According to Lewis-dot structure, there are 7 number of bonding electrons and 8 number of non-bonding electrons.
In SCN, carbon atom is the central atom and sulfur and nitrogen are the neighboring atoms.
The resonance structure of is shown below.
Answer:
the concentration of PCl5 in the equilibrium mixture = 296.20M
Explanation:
The concept of equilibrium constant was applied where the equilibrium constant is the ration of the concentration of the product over the concentration of the reactants raised to the power of their coefficients. it can be in terms of concentration in M or in terms of Pressure in atm.
The detaied steps is as shown in the attached file.
Answer:
12g of rain 12g of snow 12g of ice
Explanation:
yes this was answered by a 6th grader no joke so what happens is rain would basically classified as water so that would sink all the way to the bottom. Then snow cause that is somewhat like a solid mixed up with water so that would be second and then ice is just a plain old solid i hope i answered your question
