In an ionic compound, the attraction between actions and _________ hold the compound together
Nady [450]
Answer: 
            The correct option in blank is anion.

Explanation:
                  Ionic compound is formed by the transfer of electron from one atom to another atom. When an electropositve atom lose an electron it form cation, whereas as anion is formed when an atom gain an electron. These actions and anions then attract each other and form an ionic compound.
I hope it will help you.

Example:
              The formation of NaCl is best example of ionic compound. Na has one electron in its outer most shell which can easily be removed to form Na+, while Cl has seven electron in its outer most shell so it can easily gain an electron lost by Na to form Cl-. Then these ions attract each other and form NaCl as shown in the figure.

Help please thanks..​
jasenka [17]

Answer:

7) the environment is hypotonic because it is less concentrated than the inside of the cell

8.)the mass would decrease because the stuff inside the cell (which is more concentrated in comparison) would diffuse across the cell membrane into the environment in order to maintain equilibrium

9.) Diffusion in order to maintain equilibrium (moving things across a barrier from a more concentrated area to a less concentrated area in order to have an equal concentration on each side) does not require energy. However, moving matter out of the cell in Diagram C would require energy because it involves moving mass from a less concentrated area to a more concentrated area.
