Phosphine, ph3(g), combusts in oxygen gas to form water vapor and solid tetraphosphorus decaoxide. express your answer as a balanced chemical equation. identify all of the phases in your answer.

Answer :

barnuts

Tetraphosphorus Decaoxide has a molecular formula of P4O10, all else are known. Therefore the balanced chemical equation would be:

4PH3 + 8O2 --> 6H2O + P4O10

 

Taking into account the phases:

4PH3(g) + 8O2(g) --> 6H2O(g) + P4O10(s)
