As heat for making hot water, heating buildings and cooking.
A) NaCl = 58.44 g/mol
number of moles : 2.14 / 58.44 = 0.0366 moles
V = n / M => 0.0366 / 0.270 = 0.1355 L
__________________________________________
b) C2H6<span>O = 46.06 g/mol
</span>number of moles : 4.30 / 46.06 = 0.0933 moles
<span>V = n / M => 0.0933 / 1.50 = 0.0622 L
</span>___________________________________________
c) CH3COOH = 60.0 g/mol
number of moles : 0.85 / 60.0= 0.0141 moles
V = n / M => <span> 0.0141 </span>/ 0.30 = 0.047 L

What you can learn, is since there are 2 in the first ring of electrons, that is full, the other 6 are valence electrons which can bond with others, and want to bond with them to finish the ring of 8 electrons.
Answer is: D. solute.
In aqueous solution, solvent is water and solute (in this example carbon dioxide CO₂) is a substance dissolved in water.
The amount of solute that can be dissolved in a solvent depends of chemical composition, temperature and pressure.
Solution has a uniform composition and is able to be separated by physical means.
Answer:
B) the electron
