Answer:
D) Pressure vs. temperature
Explanation:
A phase diagram is a graph that shows the physical states of a substance under different conditions of temperature and pressure.
For example, the phase diagram below shows the different combinations of temperature and pressure under which water can exist as a solid, a liquid, or a gas.

The correct answer among the choices given is option A. Hydrochloric acid is a much stronger acid than sulfuric acid given that the concentration both is equal. This can be proved by the pKa of these acids. Hydrochloric acid has a pKa of -6 while the pKa of sulfuric acid is -3. The lower the value of the pKa, the stronger the acidity of the substance.
Answer:
An atom cannot have 0.9 of a neutron.
Explanation:
Isotope of hydrogen is Protium, 11H, which has one proton, one electron and no neutron. Another isotope of hydrogen, deuterium has one proton, one electron and one neutron. There are no elements with 0.9 neutron. It is not possible for an element to have fraction of a neutron, the neutron is always a whole number.
