Answer:
i have no clue whats going on here but imma act like i do.....
Explanation:
The motion of particles can be changed by the temperature you put it at.
The motion of molecules in a ice cube are so packed together that they can't move freely like molecules in liquids and gases
Filtration: To remove solid substance from liquid.
Evaporation: To remove dissolved substance from liquid.
Distillation: To separate 2 liquids with different boiling points.
I can tell you there certainly is enough information, so we can eliminate the fourth option right away.
Group two elements tend to form 2+ cations, and nitrogen forms 3- anions. To make a stable substance, we need those to cancel out. Calling the group 2 element X:
N2X3 would cause the charge to be 2(-3) + 3(2) = 0
This would mean 3 ions of X and 2 anions of N would be a stable ionic compound.
