Answer:
Attached in the photo.
Explanation:
Hello,
The answers in the attached photo. Just three things:
- In the second point a parenthesis is missing to properly understand the molecule (after the oxygen), nevertheless, I assumed it was an ether.
- In the sixth point, there's a missing hydrogen for it to be an ether as well.
- In the tenth point the second parenthesis is not clear, it seems there's a missing subscript, nevertheless I draw it assuming complete octates.
Best regards.
Answer:
Meteorologists use computer models to predict the weather. And computational power has come an extended way. Yet meteorologists still have trouble correctly predicting the weather over some days. Sometimes they don’t even comprehend right over 24 hours! Why does this happen? Their ability to predict the weather is restricted by the number of available data, the time available to research it, and therefore the complexity of weather events.

Answer:
- C₃H₈ (g) + 5O₂(g) → 3CO₂ (g) + 4H₂O (l)
(option D. with the proviso that the subscripts of propane's chemical formula must be corrected)
Explanation:
<em>Propane</em> is the saturated hydrocarbon, alkane, with chemical formula C₃H₈ or CH₃CH₂CH₃.
The complete combustion of the hydrocarbons yield carbon dioxide (CO₂) and water (H₂O).
The chemical equation that represents this combustion is:
- C₃H₈ (g) + O₂(g) → CO₂ (g) + H₂O (l) (skeleton equation: unbalanced)
Once you balance it, you get:
- C₃H₈ (g) + 5O₂(g) → 3CO₂ (g) + 4H₂O (l)
Left side Right side
C 3 3
H 8 4×2 = 8
O 5×2 = 10 3×2 + 4 = 10
That equation corresponds to the option D. of the list, with the proviso that the subscripts of propane's chemical formula must be corrected
Answer:
Organic chemistry is the chemistry of carbon compounds. Carbon has the ability to bond with itself to
form long chains and, as a result, millions of compounds from simple hydrocarbons to large
biomolecules such as proteins, lipids, carbohydrates, and nucleic acids. Originally it was believed that
these compounds had to come from a living organism, now they are synthesized in the laboratory.
The simplest organic compounds are composed of carbon and hydrogen and are known as hydrocarbons.
There are four types, or classes, of hydrocarbons:
Alkanes: contain all C-C single bonds. These are known as saturated hydrocarbons.
Alkenes: contain at least one C=C double bond.
Alkynes: contain at least one C≡C triple bond. Both alkenes and alkynes are known as
unsaturated hydrocarbons
Aromatic hydrocarbons: contain a benzene structure
Explanation:
A.Hydrogen Atom has 2 atoms. Ex:H2O H2O means 2 Hydrogen atoms, O means 1 oxygen atom.
B.Molecule A Molecule is 2 Atoms.
C.Diatomic Oxygen Diatomic Oxygen is a molecule,it has 2 atoms.
D.Oxygen Has 1 atom,H2O 2 Hydrogen 1 OXYGEN.
Therefor your answer is D.Oxygen Atom.
