Average velocity (v) of an object is equal to its final velocity (v) plus initial velocity (u), divided by two. Where: ¯v = average velocity.
Hope this helps :)
And could i please have brainliest
The ammonia gas is absorbed in the concentrated brine to produce aqueous sodium chloride and aqueous ammonia. This ammoniation process is exothermic, so energy is released as heat. The ammonia tower eventually needs to be cooled.
Answer:1 Boiling
Explanation:
Salt (Solute) + water (solvent) = Solution.
Salt dissolves in water, therefore, the only way to recover the salt is by boiling (evaporation) the solution.
The two types of energy changes that occur are heat and light changes.
