Answer:
Pentasulfur nonanitride.
Explanation:
In order to name a compound properly, we need to identify the type of a compound we have. The given compound consists of two non-metals, sulfur and nitrogen. This implies that we have a covalent compound in contrast to an ionic compound which consists of a metal and a non-metal.
To name a molecular/covalent compound, we should use prefixes stating the number of atoms we have. In this case, we have 5 sulfur atoms. The prefix for 5 is 'penta'. That said, we have 'pentasulfur' as our beginning of the name.
We also have 9 nitrogen atoms. The second atom in the molecular formula would have an ending of '-ide', so we expect to have 'nitride'. Adding a prefix for 9, we'd have 'nonanitride'.
Putting everything together, the name is pentasulfur nonanitride.
Some common prefixes:
mono – one (we don't state mono for the first atom, e. g., we would name CO as carbon monoxide instead of monocarbon monoxide);
di – two;
tri – three;
tetra – four;
penta – five;
hexa – six;
hepta – seven;
octa – eight;
nona – nine;
deca – ten.
Notice that 'decanitride' would be correct in case you had 10 nitrogen atoms, similarly, tetra and hexa stand for 4 and 6 instead of 5 given sulfur atoms.

i could help you if you tell me the proper question.
Pure water would be classified as non-conductor since it does not allow the flow of current into the solution. It does not contains any ions or free electrons so it cannot allow the flow of current into the system. It can allow current only when any impurities is present like salts.
