2 answers:
Explanation:
Manganese(III) oxide is a chemical compound with chemical formula .
Since, manganese is a transition metal so, in order to attain stability it will lose valence electrons and as oxygen is chemically combining with it will take up the electrons.
Hence, it will lead to the formation of an ionic compound. Therefore, oxidation state of Mn in this compound is +3 and oxidation state of oxygen is -2.
Therefore, we can conclude that Manganese(III) oxide is a transition metal compound. The oxidation state of manganese in this compound is +3, and the chemical formula of the compound is .

Taking into account the reaction stoichiometry, 340.0 moles of methane are produced when 85.1 moles of carbon dioxide gas react with excess hydrogen gas
<h3>Reaction stoichiometry</h3>In first place, the balanced reaction is:
CO₂ + 4 H₄ → CH₄ + 2 H₂O
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
- CO₂: 1 mole
- H₄: 4 moles
- CH₄: 1 mole
- H₂O: 2 moles
The following rule of three can be applied: if by reaction stoichiometry 1 mole of CO₂ form 4 moles of CH₄, 85.1 moles of CO₂ form how many moles of CH₄?
<u><em>moles of CH₄= 340.4 moles</em></u>
Then, 340.0 moles of methane are produced when 85.1 moles of carbon dioxide gas react with excess hydrogen gas
