Water exists in liquid form between its 1. Freezing and Boiling point 2. Freezing and melting point 3. Boiling and melting point
1 answer:
Answer:
Freezing and boiling point
Explanation:
A liquid form of any substance is an intermediate form between the solid form and the gaseous form.
Decreasing the temperature of liquid water according to the phase diagram of would freeze it and we would have a phase change from liquid to solid (ice) at the freezing point of water.
Similarly, heating water to its boiling point would evaporate water and we would have a phase change from liquid to gas (water vapor).
Therefore, liquid water exists between its freezing and boiling point.

Answer:
1. 0.023 M H3O+.
2. pOH = 5.52.
3. pH=9.45
4. 0.0018 M OH-
Explanation:
Hello,
In this case, such order could be computed by means of the pH, the lower the pH the more acid the solution, thus:
1. 0.0018 M OH-:
2. 0.023 M H3O+
3. pH=9.45
4.
Therefore the order is
1. 0.023 M H3O+.
2. pOH = 5.52.
3. pH=9.45
4. 0.0018 M OH-
Best regards.
