Explanation:
a. the sharing of electrons between a hydrogen atom and another atom. This description is not for hydrogen bonding, in hydrogen bonding atoms do not share electrons, to form this bond.
b. the electrostatic interaction between an atom that has lost an electron and an atom that has gained an electron. This definition is describing an ionic bonding, not a hydrogen bonding.
c. the interaction between a hydrogen atom covalently bonded to an electronegative atom and another electronegative atom. This is the right definition of hydrogen bonding, because is mentioning the interaction between a hydrogen and an electronegative atom.
Iron because it is formed by metal atoms.
B, mode since mode represents the data is the most frequent in the whole set, which in this case is 8cm
Aspartame is an artificial sweetener that is added to food and beverages as a substitute to table sugar or sucrose. It is apparently 200 times sweet than sucrose. It is also more preferable especially in the food industry because its sweetness lasts longer than sucrose does. Aspartame is a methyl ester from two acidic amino acids, aspartic acid and phenylalanine. It also constitute a small portion of methanol. The composition is 40% aspartic acid, 50% phenylalanine and 10% methanol. This compound was accidentally discovered by James Schlatter when he was trying to test an anti-ulcer drug.
