a) A proposed battery involves the reaction of Zn(s) and Cl2(g) to give ZnCl2. If you want such a battery to operate for 10 hours and deliver 1.5A current, what is the minimum mass of zinc that the anode must have?
Electronic Effects
The effect of electrons that are located in the chemical bonds within the atoms of the molecule is termed an electronic effect. The electronic effect is also explained as the effect through which the reactivity of the compound in one portion is controlled by the electron repulsion or attraction producing in another portion of the molecule.
Drawing Resonance Forms
In organic chemistry, resonance may be a mental exercise that illustrates the delocalization of electrons inside molecules within the valence bond theory of octet bonding. It entails creating several Lewis structures that, when combined, reflect the molecule's entire electronic structure. One Lewis diagram cannot explain the bonding (lone pair, double bond, octet) elaborately. A hybrid describes a combination of possible resonance structures that represents the entire delocalization of electrons within the molecule.
Using Molecular Structure To Predict Equilibrium
Equilibrium does not always imply an equal presence of reactants and products. This signifies that the reaction reaches a point when reactant and product quantities remain constant as the rate of forward and backward reaction is the same. Molecular structures of various compounds can help in predicting equilibrium.
I'm a bit confused
![### 5. Electrolysis
**a) Proposed Battery**
A proposed battery involves the reaction of zinc (Zn(s)) and chlorine gas (Cl₂(g)) to produce zinc chloride (ZnCl₂). For this battery to operate for 10 hours while delivering a current of 1.5 A, what is the minimum mass of zinc that the anode must have?
**b) Commercial Cell for F₂ Production**
A commercial cell produces fluorine (F₂) gas with a current of 1500 A from the electrolysis of hydrogen fluoride (HF) dissolved in potassium fluoride (KF).
\[
2 \text{HF (KF)} \rightarrow \text{H}_2 (g) + \text{F}_2 (g)
\]
How long must the cell run to produce 25 kg of F₂?
**c) Electrolysis of Pt⁴⁺ Solution**
A solution containing Pt⁴⁺ is electrolyzed with a current of 4.00 A. How long will it take to plate out all the platinum from a 0.50 L of a 0.010 M solution of Pt⁴⁺?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F429e9742-edc3-48a7-95f6-8a9c4ad731d8%2Fc3f46cb6-667d-4d07-911c-3c021a7c5530%2F8kwfcrb_processed.png&w=3840&q=75)
