Which pair of atoms has the highest electronegativity difference?
zavuch27 [327]
The best way to accurately determine the pair with the highest electronegativity difference is by using their corresponding electronegativity values. For the each of the choices, the difference is:

A. H-S = 2.5 - 2.1 = 0.4
B. H-Cl = 3 - 2.1 = 0.9
C. N-H = 3 - 2.1 = 0.9
D. O-H = 3.5 - 2.1 = 1.4
E. C-H = 2.5 - 2.1 = 0.4

As show, D. has the highest difference. Without looking at their values, you can also determine the pair with the highest difference by taking note of the trend of electronegativity on the periodic table. Electronegativity increases as you go right a group and up a period. This makes oxygen the most electronegative element among the other elements paired with hydrogen.

Hydrophilic molecules that are to be released by cells are stored in membrane-bound structures called:_____
ahrayia [7]

Hydrophilic molecules that are to be released by cells are stored in membrane-bound structures called <u>Secretory vesicles.</u>

<u></u>

The head, which forms the outer and inner lining, is 'hydrophilic' (water-loving), while the tail facing the interior of the cell membrane is 'hydrophobic' (water-hating).

All lipid molecules in cell membranes are amphiphilic (or amphipathic). That is, they have a hydrophilic (“water-loving”) or polar end and a hydrophobic (“hydrophobic”) or non-polar end.

Cells contain membrane-bound structures called cellular organelles and more complex chemicals. Organelles are sometimes referred to as subunits within cells designed to perform specific functions.

Channel-forming proteins can be used to facilitate the transport of water and other hydrophilic molecules. These channels are often gated to regulate transport rates. In facilitated transport, a hydrophilic molecule binds to a 'carrier' protein. This is a form of passive transport.

The molecule CH₂O contains two single bonds and one double bond. True or false
Tamiku [17]

Answer:

<em>The answer to your question is </em><em>True</em>

Explanation:

CH2O is a polar molecule. It has three polar bonds that are arranged asymmetrically, thus allowing their dipole moments to add up and give the molecule an overall dipole moment. CH2O has a central carbon atom that forms two single bonds with the two hydrogen atoms and a double bond with the oxygen atom.

<u><em>I hope this helps and have a good day!</em></u>
