There’s no element named Lk in the periodic table, I guess it’s be Lokinium Carbonate, isn’t?
I’m not sure but I thin is transpiration
Answer:

Explanation:
Na reacts with all OH groups to produce hydrogen.
The reaction with cyclobutanol is shown below.
The reaction with butanoic acid is

Both compounds release bubbles of hydrogen, so you can't use sodium to distinguish between them.
The question is: Give the systematic name of
.
Answer: The systematic name of
is diphosphorus trisulfide.
Explanation:
As the chemical formula of given compound is
. This sows that there are two phosphorus atoms so a prefix "di" will be added before the name of phosphorus atom.
Whereas there are three sulfur atoms present here. So, a prefix "tri" will be added before naming the sulfur atom. As sulfur is the anion so a suffix '-ide' will be added to its name.
Hence, name of the compound
is diphosphorus trisulfide.
Thus, we can conclude that the systematic name of
is diphosphorus trisulfide.
