put some water out with less salt and then some more water out with more salt and look at the differences with the freezing.
It's a single- replacement reaction so Mg+ 2HCl ➡️ H2+ MgCl2
The answer is (3) 11.2 L of N2(g). When the choices are all gases, the number of molecules depends on the molar number of the gas. Under the condition of STP, the molar number of a gas is depends on volume only. So the same volume of gas has the same number of molecules.

Answer:
The pOH of a solution that has a pH of 6.25 at 100°C is 7.75 (option D)
Explanation:
pOH + pH = 14
pOH = 14 - 6.25
pOH = 7.75
Therefore, at 100°C, the Kw of water is 5.6x10⁻¹³ and the pOH of a solution that has a pH of 6.25 at 100°C is 7.75.
Thus, option D, is the correct answer.
