<u>Answer:</u>

Carbon (i) : quaternary carbon

Carbon (ii) : secondary carbon

Carbon (iii) : tertiary carbon

Carbon (iv) : secondary carbon

<u>Explanation:</u>

Carbons can be classified into 4 categories:

(1) Primary carbon (1^o): These are the atoms where the carbon atom is attached to one other carbon atom.

(2) Secondary carbon (2^o): These are the atoms where the carbon atom is attached to two other carbon atoms.

(3) Tertiary carbon (3^o): These are the atoms where the carbon atom is attached to three other carbon atoms.

(4) Quaternary carbon (4^o): These are the atoms where the carbon atom is attached to four other carbon atoms.

In the given structure:

Carbon (i) is attached to 4 further carbon atoms and hence, it is a quaternary carbon.

Carbon (ii) is attached to 2 further carbon atoms and hence, it is a secondary carbon.

Carbon (iii) is attached to 3 further carbon atoms and hence, it is a tertiary carbon.

Carbon (iv) is attached to 2 further carbon atoms and hence, it is a secondary carbon.

Answer:

The correct option is: c. phospholipid      

Explanation:

Phospholipids, also known as glycerophospholipids, are the derivatives of fatty acids which is a major structural component of the cell membranes.

Phospholipid is the class of lipids that is composed of a <u>glycerol molecule that forms ester bonds with the two long-chain fatty acids and one phosphate group.</u>

<u>Therefore, Molecule A is a </u><u>phospholipid.</u>

Identify the limiting reactant when 1.22 g of O2 reacts with 1.05 g H2 to produce water.
kupik [55]
The reaction between oxygen, O2, and hydrogen, H2, to produce water can be expressed as,

                    2H2 + O2 --> 2H2O

The masses of each of the reactants are calculated below.

          2H2 = 4(1.01 g) = 4.04 g
          O2 = 2(16 g) = 32 g

Given 1.22 grams of oxygen, we determine the mass of hydrogen needed.
        (1.22 g O2)(4.04 g H2 / 32 g O2) = 0.154 g of O2

Since there are 1.05 grams of O2 then, the limiting reactant is 1.22 grams of oxygen.


<em>Answer: 1.22 g of oxygen</em>

Pretend that you are the size of an atom, observing a reaction between a potassium atom and a fluorine atom. Write an account of
Crazy boy [7]
 <span>Each atom in an ionic compound tends either to empty or complete the shell to 8 electrons. So when the number of electrons on the external shell is near 8 , the atom tends to attract electrons to complete the shell giving a positive ion called anion 
Conversely when the number of electrons is small the atom gives these electrons to form a positive ion called a cation</span>
