The ionic compound formed by sodium and sulfur is Na2S, whose name is sodium sulfide.
The chemical formula tells you the ratio between the two elements is 2Na/1S or 1S/2Na
So, if you have 6.4 * 10^22 sodium ions, you will have
6.4 * 10^22 Na * 1S / 2Na = 3.2 * 10^22 S.
Answer: the compound contains 3.2 * 10^22 sulfide ions.
Plasma forms when a gas reaches extremely high temperatures
Answer is: N₂ + 3H₂ → 2NH₃.
NH₃ is ammonia.
The Haber process is procedure for the production of ammonia, in this process atmospheric nitrogen (N₂) is converted to ammonia (NH₃):
N₂ + 3H₂ ⇄ 2NH₃ ΔrH = -92 kJ/mol.
In one molecule of the ammonia, there are three hydrogen atoms and one nitrogen atom.
Ammonia (NH₃) shows basic character in aqueous solution:
NH₃ + H₂O ⇄ NH₄⁺ + OH⁻.
