What are the differences and similarities between ionic compounds and covalent compounds?

Chemistry
1 answer:
mestny [16]4 years ago
4 0

Answer:

OK - quick version, alright? Ionic compounds are held together by virtue of the difference in their charges. Like a Salt. NaCl. Na+ plus Cl-

But Covalent compounds SHARE their electrons, like Methyl Alcohol. CH3OH. This is toxic!

Assume that Na+ is being transported across a membrane via facilitated diffusion. Which of the following conditions would allow
lesya [120]

Answer:

<h2>4. Na+ diffusing toward the side of the membrane with Cl− and 50% less Na+.</h2>

Explanation:

Facilitated diffusion is a type of transport mechanism in which the special proteins are involved and play an important role in the transport of the atoms, ions or molecules. This mechanism is based on the electrochemical gradient differences. When this difference increase, then the transport of the sodium takes place because sodium ions are chemically attracted by chloride ions. In a facilitated diffusion process, no energy requirement takes place. This process occurs along the concentration gradient.

What is a result of the unequal electron sharing in a water molecule?
alina1380 [7]

Answer:

The right choice is  c. Water molecules have a weakly positive hydrogen end.

Explanation:

The unequal sharing of electrons in water molecule gives a slight negative charge near its oxygen atom ( see image below) and a slight positive charge near its hydrogen atoms. A neutral molecule that has a partial positive charge at one end and a partial negative charge at the other, it is a polar molecule.

so

a. Water molecules have a nonpolar bond.

It is wrong choice because water has polar bond .

b. Water molecules have a weakly positive oxygen end.  

Also, a wrong choice due to water molecule gives a slight negative charge near its oxygen atom.

c. Water molecules have a weakly positive hydrogen end.  

This is the right choice.

d. Water molecules have two oxygen and two hydrogen atoms

It is wrong choice because water has one oxygen and two hydrogen atoms

So, the right choice is

c. Water molecules have a weakly positive hydrogen end.
