Write a balanced chemical equation that shows the formation of pentanoic acid from the elements carbon (C), hydrogen (H2 ) and oxygen (O2 ). (Use the smallest integer coefficients possible and do not include states. Enter the elements in the order: C, H, then O in the product box.)
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.
#### Chemical Equation
To understand the formation of pentanoic acid, we need to write a balanced chemical equation starting from the elemental components: carbon (C), hydrogen (H₂), and oxygen (O₂). Follow these instructions:
1. **Equation Structure:**
- The equation must balance the number of atoms for each element on both sides.
- Use the smallest integer coefficients possible.
- Do not include physical states (e.g., solid, liquid, gas) in the equation.
2. **Order:**
- Enter the elements in the product box in the following order: Carbon (C), Hydrogen (H), Oxygen (O).
#### Balanced Chemical Equation
Fill in the blanks with the correct coefficients and molecular formulas:
\[ \boxed{6} \text{C} + \boxed{7} \text{H}_2 + \boxed{3} \text{O}_2 \rightarrow \boxed{C}_5\boxed{H}_1\boxed{0}\boxed{O}_2 \]
This represents:
\[ 6C + 7H_2 + 3O_2 \rightarrow C_5H_{10}O_2 \]
Make sure the number of atoms of each element on the reactant side equals the number of atoms on the product side to ensure the equation is balanced.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F1f61489d-b599-4717-b8e4-1c0e8dbf11ad%2Fe63b4b1d-944c-418e-ad8c-61865b4bc3a5%2Fkaf5x6i.png&w=3840&q=75)
