Answer:
A, F, H
Explanation:
Hydrogen bonding occurs between compounds that make N-H, O-H, and F-H bonds. Just because a compound has a N, O, and F atom in the molecule doesn't mean that the compound will exhibit hydrogen bonding. The N, O, or F must be bonded to a hydrogen. Carbon-hydrogen bonds do not cause hydrogen bonding.
This means that A, F, and H will have hydrogen bonding.
Formation of a precipitate
Answer:
the atomic mass of an element is the average mass of the atoms of an element measured in atomic mass unit (amu, also known as daltons, D). The atomic mass is a weighted average of all of the isotopes of that element, in which the mass of each isotope is multiplied by the abundance of that particular isotope
Explanation:
Average atomic mass = f1M1 + f2M2 + … + fnMn where f is the fraction representing the natural abundance of the isotope and M is the mass number (weight) of the isotope. The average atomic mass of an element can be found on the periodic table, typically under the elemental symbol.
