A. A diagram showing the effects of temperature and pressure on phase
Explanation:
A phase diagram is a diagram that shows the effects of temperature and pressure on phase.
- A phase diagram shows how different substances are transformed from one form to another.
- The transformation is an interplay between pressure and temperature.
- The phase graph represents physical state changes.
- A phase change is made up of pressure on the y-axis and temperature on the x - axis.

Atomic mass Sodium ( Na ) = 22.98 u.m.a
22.98 g ----------------- 6.02x10²³ atoms
175 g ------------------- ?? atoms
175 x ( 6.02x10²³) / 22.98 =
4.58x10²⁴ atoms of Na
hope this helps!
I believe it’s c for warm front then f for cold front. I hope that helps!
<span>NaCl is poster-compound for ionic bonding. The bonds in NaCl have about 70% ionic character, making the bond highly polar. its overstatement to state that there is actual ion in NaCl with +1 and -1 charge but actual charge of Na and Cl is +1 and -1 ion, since Nacl exist as a network of highly charged particle and not discrete molecule, NaCl particle does not exhibit intermolecular forces.
Water molecule on other hand exhibit London dispersion force, keesom force, and hydrogen bonding.
The polar water molecule are attracted to the polarized Na and Cl atoms. This is what allow NaCl(s) to dissolve and ionize in water. Therefore type of attraction in NaCl is ion-dipole attraction.</span>
