Hey! The answer you are looking for today is D.
Here is why;
A heating curve graphically represents the phase transitions that a substance is undergoing as heat is added to it. The plateaus on the curve mark, the phase changes. The temperature remains constant during these phase transitions.
Hope I made your day a bit easier,
Have a nice day and Happy Halloween!

Answer:
Neutrons
Explanation:
Isotopes are atoms with same protons and different neutron number. For eg: Hydrogen has 0 neutrons. But a stable isotope of hydrogen called Deuterium has 1 neutron but both still have 1 proton which makes them isotopes.
Explanation:
The generated Na+ and OH-ions are immediately surrounded by molecules of water (typically 6, each). There is the development of the exothermic hydration sphere for each ion. It seems as though there is negative overall energy of dissolving solid NaOH.
Now, since this dissolution is exothermic the temperature of the mixture rises.
