<span>In the formation of a solution,
energy is required to overcome the forces of attraction between the solvent
particles. The first step is for the solvent particles to move in order for
solute particles to enter the system. This process is endothermic where energy
flows into the system. The second step is when solute particles must separate
from other solute particles. Lastly, the solute should move between solvent
particles.</span>
Computers don’t have the ability to see as much as we do and in Construction sites this can be very dangerous if your driverless car has not been properly updated in an area where there’s a lot of construction you can we put into harms way. The lanes may have changed and they will not have the data to be able to recognize this in time and you could get into a serious car crash.
The answer is B Nitrogen atoms will form three covalent bonds (also called triple covalent) between two atoms of nitrogen because each nitrogen atom needs three electrons to fill its outermost shell. Another example of a nonpolar covalent bond is found in the methane (CH4) molecule.
