Answer:
Explanation:
Canyons form through processes of erosion, although in a few instances they can be caused by the movement of tectonic plates. A canyon starts out as a riverbed, and over centuries of time, the river cuts more and more deeply into the rock, creating a deep gorge.

If you mark those points on the phase diagram it appears to be moving from vapor to liquid. If you can’t see how I determined that please let me know and I can further explain.
Vapor to liquid is the same as saying gas to liquid, which I believe to be the correct answer.
Molality is defined as the number of moles of solute in 1 kg of solvent.
molality of solution to be prepared is 0.50 molal
this means that in 1000 g of water there should be 0.50 mol of NaCl
if 1000 g of water should contain - 0.50 mol
then 750.0 g of water requires - 0.50 mol/kg x 0.750 kg = 0.375 mol
mass of NaCl in 0.375 mol - 58.5 g/mol x 0.375 mol = 21.9 g
therefore a mass of 21.9 g of NaCl is required
Ten protons would be Neon, but the most stable? I'd have to say 12 neutrons in contrast to the 10 protons. Not too negative in balance.
