Question

Write the word, formula, and chemical equations for the reaction between hydrogen sulfide gas and oxygen gas that produces sulfur dioxide gas and water vapor. Critical Thinking 5. INTEGRATING CONCEPTS The reaction of vanadium(II) oxide with iron(III) oxide results in the formation of vanadium(V) oxide and iron(II) oxide. Write the balanced chemical equation.

Answer 1

The balanced equations for the reactions are outlined below:

Step-by-step explanation:

A balanced equation describes how many (number of moles) atoms of the reactant give rise to how many (number of moles) of product.

1. Hydrogen sulfide gas (
   `H_(2)S`) and oxygen gas (
   `O_(2)`) react to produce sulfur dioxide gas (
   `SO_(2)`) and water vapor gas.
2. The balanced equation for the reaction, taking into consideration the states is:

`2H_(2)S(g) + 3O_(2)(g)` →
`2SO_(2)(g) + 2H_(2)O(g)`

Vanadium(II) oxide (VO) is oxidized by iron(III) oxide (Fe2O3) resulting in the formation of vanadium(V) oxide (V2O5) and iron(II) oxide (FeO).

The balanced equation:

`2VO + 3Fe_(2)O_(3)` →
`V_(2) O_(5) + 6FeO`
