a Write a balanced chemical equation for the formation of 1 mol of Cr2O3(s) from Cr and O2 in their standard states. (Be sure to specify states such as (ag) or (s). If a box is not needed, leave it blank. If no reaction occurs, leave all boxes blank and click on Submit.)
Thermochemistry
Thermochemistry can be considered as a branch of thermodynamics that deals with the connections between warmth, work, and various types of energy, formed because of different synthetic and actual cycles. Thermochemistry describes the energy changes that occur as a result of reactions or chemical changes in a substance.
Exergonic Reaction
The term exergonic is derived from the Greek word in which ‘ergon’ means work and exergonic means ‘work outside’. Exergonic reactions releases work energy. Exergonic reactions are different from exothermic reactions, the one that releases only heat energy during the course of the reaction. So, exothermic reaction is one type of exergonic reaction. Exergonic reaction releases work energy in different forms like heat, light or sound. For example, a glow stick releases light making that an exergonic reaction and not an exothermic reaction since no heat is released. Even endothermic reactions at very high temperature are exergonic.

**Question:**
Write a balanced chemical equation for the formation of 1 mol of Cr₂O₃(s) from Cr and O₂ in their standard states.
(Be sure to specify states such as (aq) or (s). If a box is not needed, leave it blank. If no reaction occurs, leave all boxes blank and click on Submit.)
**Equation:**
\[ \text{[Box]} \quad + \quad \text{[Box]} \quad \longrightarrow \quad \text{[Box]} \]

**Explanation:**
- The diagram shows a reaction equation with three boxes. The first two boxes represent reactants, and the third box represents the product.
- The plus sign "+" between the first two boxes indicates that the reactants are combined to form the product in the third box, shown with an arrow "→".
- Students are required to fill in the boxes with the balanced chemical equation using the provided reactants and product, including their physical states.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F80a03a3c-a3f7-46eb-aa8a-9b17c8beb70c%2F609d5adb-4f48-4edb-9b48-33135c5e06f9%2Fobigl3r_processed.png&w=3840&q=75)
