A particle of light is called a photon. I hope this helps! Please mark branliest!! ❤️
B. is positive
H20 (l)--> H20 (g)
when that happens, the heat is absorbed into the liquid to change the state of the liquid to gas; therefore, in order to change to a gaseous state, heat must be a reactant. and so enthalpy is increasing
The ph of the solution would be 8
Filtration, is a chemical process where you are separating a precipitate from a solution.
As a general rule:
"Solubility of compounds decrease with the increasing of temperature" as you can see in the graph
Now, if you want to recover benzoic acid from an aqueous solution, the better option would be with Ice cold water because its solubility will be lower producing more precipitate.
