Answer:
Secondary structure
Explanation:
Stricture of proteins can be categories into 4
Primary structure, secondary structure, tertiary structure and quaternary structure.
Primary structure are polypeptide chains. The polypeptide chains are formed by amino acids held together by peptide bonds.
Secondary structure refers to the folding of polypeptides chains. Two most common secondary structures are alpha helix and beta pleated structure. These folding occurs because of hydrogen bonding between the oxygen of the carbonyl of one amino acid and the hydrogen of another amino acid.
Therefore, hydrogen bonding is crucial for secondary structure of the protein.
Answer:
Moles of substance are defined ratio of the given mass of the substance to the molar mass of the substance.
Given :
The 52.06 grams of carbon dioxide.
To find :
The moles of carbon dioxide.
Solution:
The mass of carbon dioxide = 52.06 g
The molar mass of carbon dioxide = 44.01 g/mol
The moles of carbon dioxide:
1.183 moles of carbon dioxide are there in 52.06 g of carbon dioxide.
Explanation:

Answer:
A flame test of a colorless solution gives a bright yellow color. When reacted with AgNO, a white precipitate forms that dissolves when HNO, is added.
Increasing order of magnitude of lattice energy is rbi <K2s< Mgs < Ga2O3.
Lattice energy is the energy change upon the formation of one mole of a crystalline ionic compound from its constituent ions. It depends upon the charges of the ion and the distance between the center of the ion when they are packed in the form crystal. Basically lattice energy is determined by the charge of the atom and the atomic radii of the atoms.
In Ga2O3, Ga has 3+ and O has 2- ions .so it has the lattice energy of 6.this is calculated by multiplying q1 and q2 .this attracts strongly.
In rbI , R has +1 and i has -1.so it ha lattice energy of -1.ther is no strong attraction nor lattice energy.
In Mgs, Mg has +2 and s has -2 .this is not as strong as Ga2o3 but stronger than rbi.
In K2S, k has =1 and s has 2-.this is stronger than rbi.
