Given the unbalanced equation CO2 + H2→ CH4 + H20 (a) How many moles of water can be produced from 16 moles of carbon dioxide? (b) How many moles of CH4 will be produced along with 12 moles of water?
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.
![**Paired Exercise 9.9**
Given the unbalanced equation:
\[ \text{CO}_2 + \text{H}_2 \rightarrow \text{CH}_4 + \text{H}_2\text{O} \]
**(a)** How many moles of water can be produced from 16 moles of carbon dioxide?
\[ \quad \boxed{} \]
**(b)** How many moles of \(\text{CH}_4\) will be produced along with 12 moles of water?
\[ \quad \boxed{} \]
**Explanation:**
This exercise involves solving stoichiometric problems using the given unbalanced chemical equation. The students are required to determine the amount of products formed when given the amount of reactants. To solve these problems, the equation should first be balanced, and then the mole ratios should be used to find the answers.
**Note:** Ensure to balance the chemical equation before performing any calculations to get accurate results.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F2f9e96de-8215-4532-a7d0-6f1fdf87f241%2F4025fb69-6a3a-4aca-a971-ce37ea959eeb%2Frm92fds.png&w=3840&q=75)
