Answser: the representative unit of carbon dioxide is the molecule CO₂.


Justification:


1) carbon dioxide is made of one atom of carbon and two atoms of oxygen chemically bonded by covalent bonds.


2) A molecule is formed when two or more atoms are bonded by covalent bonds.


3) Some other examples of molecules are: water (H₂O), oxygen (O₂), the fats, the carbohydrates, glucose.


4) The term molecule is reserved for atoms bonded by covalent bonds, so ionic compounds like NaCl, are not named molecules. NaCl is told to represent a formula unit instead of a molecule.

Alla [95]

The question is incomplete, complete question is :

In an organic structure, you can classify each of the carbons as follows: Primary carbon (1°) = carbon bonded to just 1 other carbon group Secondary carbon (2°) = carbon bonded to 2 other carbon groups Tertiary carbon (3°) = carbon bonded to 3 other carbon groups Quaternary carbon (4°) = carbon bonded to 4 other carbon groups How many carbons of each classification are in the structure below? How many total carbons are in the structure? How many primary carbons are in the structure? How many secondary carbons are in the structure? How many tertiary carbons are in the structure? How many quaternary carbons are in the structure?

Structure is given in an image?

Answer:

There are 10 carbon atoms in the given structures out of which 6 are 1° , 1 is 2° , 2 are 3° and 1 is 4°.

Explanation:

Total numbers of carbon = 10

Number of primary carbons that is carbon joined to just single carbon atom = 6

Number of secondary carbons that is carbon joined to two carbon atoms = 1

Number of tertiary carbons that is carbon joined to three carbon atoms = 2

Number of quartenary carbons that is carbon joined to four carbon atoms = 1

So, there are 10 carbon atoms in the given structures out of which 6 are 1° , 1 is 2° , 2 are 3° and 1 is 4°.

How does the atmosphere help to make Earth livable? Check all that apply.
Likurg_2 [28]

Answer:

- contains oxygen

- provides warmth

- blocks harmful energy from the Sun

Explanation:

The atmosphere is crucial when it comes to providing living conditions on Earth. The gases in the atmosphere manage to balance the things just about right, so that the life can thrive. The atmosphere has oxygen, the gas that is used by pretty much every organism to be able to function. With its greenhouse gases, the atmosphere manages to trap the heat inside, thus providing warmth to the Earth. The numerous layers of the atmosphere manage to block in big portion the harmful energy from the Sun, with a special accent on the ozone layer, a layer that manages to stop most of the UV radiation.

Aqueous Solution - The expected precipitate would consist of Cu(OH)2.

What is aqueous solution?

An aqueous solution is one in which water serves as the solvent. Chemical equations typically illustrate it by adding (aq) to the appropriate chemical formula. For instance, Na+(aq) + Cl would be used to represent a solution of table salt, as well as sodium chloride (NaCl), throughout water (aq). The word aqueous, which derives from the word aqua, means that it is dissolved in or related to water. Water is a common solvent in chemistry due to its superior solvent properties and natural abundance. Since water is frequently used as a solvent in experiments, unless the solvent is specified, the word "solution" refers to an aqueous solution. A solution wherein the solvent is a liquid but not water is referred to as a non-aqueous solution.
