Question

name the following compound
p₂o₂

question 2

name the following compound
p₄s₃

Explanation:

Step1: Name the first element

For \(P_2O_5\), the first element is phosphorus (\(P\)). Since there are 2 phosphorus atoms, we use the prefix "di -". So it's "diphosphorus".

Step2: Name the second element

The second element is oxygen (\(O\)). There are 5 oxygen atoms. The prefix for 5 is "penta -", and we change the ending of oxygen to " - oxide". So it's "pentoxide".
Combining these, \(P_2O_5\) is diphosphorus pentoxide.

Step3: Name the first element for \(P_4S_3\)

For \(P_4S_3\), the first element is phosphorus (\(P\)). With 4 phosphorus atoms, the prefix is "tetra -". So it's "tetraphosphorus".

Step4: Name the second element for \(P_4S_3\)

The second element is sulfur (\(S\)). There are 3 sulfur atoms. The prefix for 3 is "tri -", and we change the ending of sulfur to " - sulfide". So it's "trisulfide".
Combining these, \(P_4S_3\) is tetraphosphorus trisulfide.

Answer:

\(P_2O_5\): diphosphorus pentoxide
\(P_4S_3\): tetraphosphorus trisulfide
