bonufazy [111]

Answer:

-The stronger electrostatic forces of attraction between the oppositely charged ions causes the Sodium chloride to break apart until it completely dissolves in the water.

Explanation:

-Sodium Chloride has positively charged sodium ions, Na^+ and negatively charged chloride ions, Cl^-.

-Water on the other hand has positively charged Hydrogen ions,H^+ and negatively charged Oxygen ions, O^{2-} due to the difference in electroneganivity.

-When dissolved in water, the positively charged sodium ions will attract the partially negatively charged oxygen ions. The negatively charged chloride ions will be attracted to the positively charged hydrogen ions in the reaction as below:

NaCl+H_2O->NaOH+HCL\\\\Na^++Cl^-+H_2O->Na^++(OH)^-+H^++Cl^-

juin [17]

The correct answer is C. Living things are composed of cells.

Explanation:

A conclusion is an idea derived from information, this idea or statement often summarizes the information or indicates the result of this. In the case of the studies by Schwann and Schleiden, these two focused on living organisms. Moreover, in both studies, the researchers found different living organisms were composed of basic life units known as cells.

In this context, one idea that derives from the findings of the two studies is "Living things are composed of cells". Also, this conclusion is now part of modern cell theory because the basic unit of life is the cell and cells can be found in all living organisms despite the type of organism (animal, plant, fungi,etc.)
