To the top. Common knowledge my dude. Heat always rises to the top.
D) reacts with oxygen
All other are physical properties.
Answer:
1. salt bridge - tertiary structure
2. amide bond - primary structure
3. disulfide bond - tertiary structure
4. beta-pleated sheet - secondary structure
5. alpha helix - secondary structure
Explanation:
A salt bridge is simply a neutralisation reaction between two molecules of opposite charge. Examples are: carboxylate ion end (RCOO−) of either aspartic acid or glutamic acid and ammonium ion end (RNH3+) from lysine or guanidinium (RNHC(NH2)2+) of arginine. The disulfide bond is usually gound in the Cysteine amino acid with the structure R−S−S−R′. Also, it is usually derived by the bonding of two thiol groups. They are both important components of protein and they determine the overall structure of protein and hence its fold.
For beta-pleated and alpha-helix structures, they are usually defined by the varying patterns of hydrogen bonds between the amine- (-NH2) and carboxyl-(-COOH) groups which are at the side chain of the amino acids. They determine the geometry of the protein hence why they are secondary structures.
Amide bond is an unbranched sequence of amide(peptide) bonds which form long chains of polypeptides (polyamides). This shows that it is a primary structure. They are also formed by dehydration where the amine- (-NH2) and carboxyl-(-COOH) groups bonds together to form a peptide bond with the loss of water.
Answer:
1
Explanation:
The empirical formula describes the simplest whole number ratio of each type of atom in a compound. To find this formula, you need to (1) convert grams of each element to moles (via their atomic masses) and then (2) find the ratio of each element (by dividing each molar value by the smallest mole value).
(Step 1)
Atomic Mass (Zn): 65.380 g/mol
Atomic Mass (C): 12.011 g/mol
Atomic Mass (O): 15.998 g/mol
10.40 grams Zn 1 mole
------------------------ x ------------------------ = 0.159 moles Zn
65.380 grams
1.92 grams C 1 mole
--------------------- x ----------------------- = 0.160 moles C
12.011 grams
7.68 grams O 1 mole
---------------------- x ------------------------ = 0.480 moles O
15.998 grams
(Step 2)
0.159 moles Zn / 0.159 = 1 atom Zn
0.160 moles C / 0.159 = 1 atom C
0.480 moles O / 0.159 = 3 atom O
The empirical formula is Zn₁C₁O₃. Therefore, the value that should be in the space is 1.
