Answer:
The most state has the high volume is the gas state.
So here the answer is vaporization!!!!
Explanation:
The most state has the high volume is the gas state.
So here the answer is between vaporization and sublimation???
and when the sublimation is: the change of the material from the solid state to the gas state directly without pass to liquid state from the solid first then to the gas
and the vaporization is : The change of the material from the liquid state to the gas state by heating Ex: water vaporize at 100°
here, the answer is sublimation because the difference of volume which resulted from this process is more than the volume resulted from vaporization.
Plz mark brainlist!!
Answer:
1
Explanation:
I would say 1 because that configuration has 7 valence electrons. The goal of the atom is to gain a full octet so it just needs to gain 1 more electron to get the full octet. To get the one electron to fill the valence shell it would only need to have 1 covalent bond.
I hope this helps. Let me know if anything is unclear.
