For the reaction between solid tetraphosphorus trisulfide

Solution 90P

Here we have to write a balanced equation  for the reaction between solid tetraphosphorus trisulfide and oxygen gas to form solid tetraphosphorus decaoxide and sulfur dioxide gas and have to show the equation in terms of (a) molecules, (b) moles, and (c) grams.

Step 1

The balanced chemical equation for the reaction between solid tetraphosphorus trisulfide (P4S3) and oxygen gas (O2) to form solid tetraphosphorus decaoxide  (P4O10) and sulfur dioxide (SO2) gas is given below,

P4S3 (s) + 8 O2 (g) → P4O10 (s) + 3 SO2 (s)

(a) Equation in term of molecules:-

1 molecule of P4S3 (s) + 8 molecules of O2(g) → 1 molecules of P4O10 (s) + 3 molecules of SO2 (s)
