Answer:
The pressure equilibrium constant (Kp) = (P O₂)³/(P CO₂)²(P H₂O)⁴.
Explanation:
2CO₂ (g) + 4H₂O (g) → 2CH₃OH (l) + 3O₂ (g).
The pressure equilibrium constant (Kp) = the product of the pressure of the products side components / the product of the pressure of the reactantss side components.
each one is raised to a power equal to its coefficient.
∴ The pressure equilibrium constant (Kp) = (P O₂)³/(P CO₂)²(P H₂O)⁴.
A flashlight battery is an example of a chemical battery, specifically a type of electrochemical cell. It converts chemical energy into electrical energy through a chemical reaction.
Inside the battery, there are two electrodes, typically made of different metals or metal compounds, and an electrolyte solution. When the battery is connected to a circuit, a chemical reaction occurs at the electrodes, resulting in the flow of electrons from one electrode to the other.
This flow of electrons generates an electric current that powers the flashlight or any other device connected to the battery.
The chemical reaction within the battery is reversible, meaning it can be recharged by applying an external electrical current to reverse the reaction and restore the chemical energy within the battery.
In summary, a flashlight battery is an example of a chemical battery because it utilizes a chemical reaction to convert chemical energy into electrical energy for powering electrical devices.
