Question

Which of the following is the correct skeleton equation for the reaction that takes place when solid phosphorus combines with oxygen gas to form diphosphorus pentoxide?A. P(s) + O2(g) --> P2O5(s)B. P2O5(s) --> P2(s) + O2(g)C. P(s) + O(g) --> P5O2(g)D. P(s) + O2(g) --> PO2(g)

Answer 1

Answer:

A. $P_{(s)}+O_2_{(g)}\rightarrow P_2O_5_{(s)}$

Explanation:

Symbolic representation of the chemical reaction with the help of the formulas and symbols is known as chemical equation. In the chemical equation, reactants are written at left-hand side as well as products are expressed or written on right-hand side. The coefficients which are written before the formulas or the symbols are known as stoichiometric numbers.

The equation of for the reaction that takes place when solid phosphorus $P_{(s)}$ combines with oxygen gas $O_2_{(g)}$ to form diphosphorus pentoxide $P_2O_5_{(s)}$ is:-

A. $P_{(s)}+O_2_{(g)}\rightarrow P_2O_5_{(s)}$
