Fossil fuels—such as coal, oil, and natural gas—come from ancient, and long dead, plant and animal matter. These fuels have been generated through millions of years of the Earth's geologic processes. Most fossil fuel reserves are found underground, relatively close to the Earth's surface.

Two scientists are investigating the properties of water. In one experiment, they notice that water breaks down to hydrogen and oxygen gas during a chemical reaction. Which of the following does this experiment demonstrate
A. it demonstrates that a water molecule consists of two hydrogen atoms and one oxygen atom.
B. it demonstrates that water consists of atoms
C. it demonstrates that water is a compound
D. it demonstrates that water is an element
Answers
Answer:
A
Explanation:
Explain why, at room temperature, CO2 is a gas and CS2 is a liquid. You may use diagrams as part of your explanation.
Answers
Explanation:
A. Hydrogen bonding is present in CS2 but not in CO2.
B. CS2 has greater dipole moment than CO2 and thus the dipole-dipole forces in CS2 are stronger.
C. CS2 partly dissociates to form ions and CO2 does not. Therefore, ion-dipole interactions are present in CS2 but not in CO2.
D. The dispersion forces are greater in CS2 than in CO2.

5. Element X has two isotopes: X-100 and X-104. If the atomic mass of X is 101
amu, what is the relative abundance of each isotope in nature?
Answers
Answer:
The abundance of X-100 is 75 percent, and X-104 has an abundance of 25 percent. The answers are found by solving two equations with two unknowns, which are A plus B equals 100, and 100A plus 104B equals 10,100.
The relative abundance of each isotope in nature
X-100 = 75%
X-104=25%
By dividing the total number of ions identified by the number of ions with a particular m/z m/z m/z ratio, one may determine the relative abundance for each individual ion in the sample.
How can the abundance of two isotopes be determined?
For chemistry problems involving relative abundance, use the following formula:
(M1)(x) + (M2)(1-x) = M (E)
Find the relative abundance of the isotopes if one nitrogen isotope, nitrogen-14, has a mass of 14.003 amu and another, nitrogen-15, has a mass of 15.000 amu.
Algebra can be used to find x. ...
x = 0.996

Which property accounts for the fact that atoms can be identified by an examination
of the emission spectrum?
A. Each kind of atom has a different mass number.
B.Each kind of atom has a different atomic number.
C.Each kind of atom has a different isotopes.
D. Each kind of atom has a characteristic difference in energy levels for electrons.
Answers
Answer:
Explanation:
D is the answer
Each kind of atom has a characteristic difference in energy levels for electrons, this property accounts for the fact that atoms can be identified by an examination, therefore the correct answer is option D.
What is the photoelectric effect?It is the process of emission of electrons from the material because of absorption of electromagnetic radiation in form of photons of light waves.
The photoelectric effect explains the particle behavior of the light waves.
Each kind of atom has a characteristic difference in energy levels for electrons this fact can be used to identify the different atoms by using inspection.
Thus, the correct answer is option D.

If a cell has 4 chromosomes at the beginning of meiosis, how many chromosomes will be in each cell at the end of meiosis?
Answers
Answer:2. Mitosis would produce identical daughter cells with the same number as the parent cell. Meiosis would product sex cells with one-half the amount of genetic material as the parent cells.
Explanation:
If a cell has 4 chromosomes at the beginning of meiosis then the daughter cell will have TWO chromosomes at the end of meiosis.
Meiosis is a type of reductional cell division by which a parental cell duplicates its genetic material (DNA) and then divides twice to produce four (4) daughter cells having half of the genetic material.These successive cell division cycles are known as Meiosis I and Meiosis II.Meiosis is a sexual mode of reproduction that produces gametes or geminal cells, which fuse during the process of fertilization to form a zygote.
In conclusion, if a cell has 4 chromosomes at the beginning of meiosis then the daughter cell will have TWO chromosomes at the end of meiosis.

how can you tell the number covalent bonds the atoms of an element can form?
Answers
how to tell how many valence electrons an atom has?
Answers
Answer: Count only the electrons in the highest shell s and p orbitals when determining valence.
Explanation: I'm glad you asked this question. It is often not well explained. The term valence electrons is assigned to only the electrons in an element's highest energy level. These reside only in the s and p orbitals, and not the d or f, as I'll explain later. The s orbital can hold 2 electrons and the p can hold 6. Potassium, K, has an s orbital in its highest energy shell, 4. It contains only 1 electron, so it has a valency of 1.
Calcium, Ca, has 2 in its highest energy level: 4s^2, so it has a valency of 2. Moving to the right, the element scandium, Sc, add another electron, but it goes into the 3d orbital. 3d is in the 3rd energy shell, so it is not counted as a valence electron. Only after we move further right, to gallium, Ga, do we start adding electrons to the 4th energy level again - the 4p orbitals can accept up to 6 electrons. Ga has 3 valence electrons - 2 in the 4s and 1 in the 4p. Oxygen has 2 in the 2s and 4 in the 4p orbitals, for a total of 6. It is close to having a comple outer shell (2 in the 2s and 6 in the 2p). Just 2 more electrons would fill both the 2s and 2p orbitals for a total of 8 valence electrons, a stable configuration (the same configuration as thje stable gas Neon).
