My teacher gave out this assignment and im having problems answering the questions…

Until the last decade, most biologists adopted a taxonomic scheme that divided the diversity of life into five kingdoms. Do to new methods, such as comparing the DNA sequences of diverse species, the kingdoms of life can now be grouped into three even higher levels of classification called domains.
a. Identify the five kingdoms and how they fit into the three domains.
b. Identify whether the five kingdoms and three domains consists of prokaryotes or eukaryotes.
c. Compare and contrast prokaryotes and eukaryotes.
d. Compare and contrast the three domains.

Each element consists of a certain kind of atom that is different from the atoms of any other element. An atom is the smallest unit of matter that still retains the properties of an element.
e. Describe the structure of an oxygen atom (Be sure to include the location, charge, and number of subatomic particles).
f. A nitrogen atom has 7 protons, and the most common isotope of nitrogen has 7 neutrons. A radioactive isotope of nitrogen has 8 neutrons. What is the atomic number and mass number of this radioactive nitrogen?
g. Describe the relationship between energy and electron location.
h. Explain why table salt is a compound, while the oxygen we breathe is not.

Water is so common that it is easy to overlook the fact that it is an exceptional substance with many extraordinary qualities. Following the theme of emergent properties, we can trace water′s unique behavior to the structure and interactions of its molecules.
i. Explain the relationship between electronegativity and the structure of water.
j. Explain the relationship between the structure of water and the four emergent properties of water.

Although the dissociation of water is reversible and statistically rare, it is exceedingly important in the chemistry of life.
k. Describe the dissociation of water.
l. Explain the relationship between hydrogen and hydroxide concentration and acids and bases.
m. Define pH and describe the pH scale.
