The answer is true because if you look at the question what does it say
Explanation:
6 F2------->4 AlF3
F2-----------> 4/6 AlF3
8.25 F2 ---------> 4×8.25/6 AlF3
so 5.5 moles
In pure water, all of the molecules in the liquid are water molecules so the mole fraction is 1 (100 % H2O, 55 mol/L). In sea water, the concentration of water molecules in the solution is less than that of pure water so the vapor pressure of sea water is also lower.
Answer:
Chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. These processes are called chemical reactions and, in general, are not reversible except by further chemical reactions.
