Modes of conduction of substances, common terms used in electrolysis

## Modes of Conduction in Substances:

There are three main modes of conduction observed in different substances:

**1. Metallic Conduction:**

* **Description:** Involves the movement of **free electrons** within a metallic lattice. These electrons are not bound to any specific atom and can move freely throughout the metal.
* **Examples:** Metals like copper, aluminum, and silver are good conductors of electricity due to the presence of a large number of free electrons.

**2. Ionic Conduction:**

* **Description:** Occurs in **electrolytes** (molten salts or ionic solutions) where **ions** move through the solution carrying the charge.
* **Examples:** Aqueous solutions of salts like NaCl or molten salts like NaCl (liquid) conduct electricity through the movement of Na⁺ and Cl⁻ ions.

**3. Electronic Conduction in Semiconductors:**

* **Description:** Involves the movement of both **electrons** and **holes** (the absence of an electron in the valence band) in semiconductors. The conductivity can be controlled by applying external factors like doping or electric fields.
* **Examples:** Materials like silicon and germanium exhibit semiconducting behavior, where their conductivity can be tailored for various applications in electronics.

## Common Terms Used in Electrolysis:

* **Electrolyte:** A substance that conducts electricity due to the presence of free ions.
* **Electrode:** An electrical conductor that is in contact with an electrolyte.
* **Anode:** The positive electrode where oxidation occurs.
* **Cathode:** The negative electrode where reduction occurs.
* **Electrolysis:** The process of using electrical energy to drive a non-spontaneous chemical reaction.
* **Electrolysis products:** The substances formed at the electrodes during electrolysis.
* **Electrolytic cell:** A device used to carry out electrolysis, consisting of electrodes, an electrolyte, and a power source.
* **Aqueous electrolysis:** Electrolysis involving water as the electrolyte.
* **Electroplating:** The deposition of a metal onto the cathode from a metal-containing solution.
* **Electrorefining:** The purification of a metal by removing impurities that go into the solution during electrolysis.

Understanding these terms and the different modes of conduction is crucial for comprehending the principles and applications of electrolysis in various fields like electroplating, battery technology, and chemical production.

This video looks to seek where Sin (Sine), Cos and Tan actually come from. Looking at the ratios of the sides of right angle triangles, we can notice certain patterns if we measure different right angle triangles with the same angles. Very similar to how ratios exist in circles with circumference and diameter to discover Pi.We can then make trig (trigonometry) tables for all the angles and then draw the graph of sin(x) which forms the sine wave.These trig ratios help us finding missing angles or sides in triangles by using SOHCAHTOA (SOH CAH TOA). The sine function can be obtained by taking ratios of triangle sides at different angles.Media, business and educational enquiries can be made to info@syedinstitute.comThank you for watching.

- Temperature has a significant impact on the rate of a chemical reaction.
- As the temperature increases, the rate of the reaction generally increases.
- Higher temperatures provide more energy to reactant molecules, allowing them to overcome activation energy barriers more easily and collide with greater frequency.
- This leads to more successful collisions and a faster reaction rate.
- The relationship between temperature and reaction rate is often described by the Arrhenius equation: k = Ae^(-Ea/RT), where k is the rate constant, A is the pre-exponential factor, Ea is the activation energy, R is the gas constant, and T is the absolute temperature.
- Temperature also influences the rate of elementary reaction steps and influences the equilibrium position of reversible reactions.
- However, extremely high temperatures can also cause unwanted side reactions or decomposition of reactants.
- It's important to note that the specific effect of temperature on the rate of a reaction depends on the nature of the reaction, the reactants, and the presence of catalysts or inhibitors.

Kasese is a district in western Uganda that is blessed with a variety of tourist attractions, including:

* The Rwenzori Mountains, Africa's third-highest mountain range, are a UNESCO World Heritage Site. The mountains are home to glaciers, snow-capped peaks, and a variety of ecosystems. Hiking, mountaineering, and sightseeing are all popular activities in the Rwenzoris.


* Queen Elizabeth National Park is one of Uganda's most popular national parks. The park is home to a wide variety of wildlife, including lions, elephants, buffaloes, and chimpanzees. Visitors can enjoy game drives, boat cruises on the Kazinga Channel, and chimpanzee trekking in Queen Elizabeth National Park.

* The Kazinga Channel is a 32-kilometer channel that connects Lake George and Lake Edward. The channel is home to a large population of hippos and crocodiles, and visitors can enjoy boat cruises on the channel to see these animals.


* The Amabere Caves are a series of caves located near Kasese. The caves are named after their stalactites, which some people believe resemble breasts. The caves are a popular spot for hiking and sightseeing.

* The Semliki Valley National Park is a small national park located on the border between Uganda and the Democratic Republic of the Congo. The park is home to a variety of primates, including chimpanzees and bonobos. Visitors can enjoy hiking, chimpanzee trekking, and birding in Semliki Valley National Park.

These are just a few of the many tourist attractions in Kasese. With its stunning scenery, diverse wildlife, and rich culture, Kasese is a great destination for travelers looking for an adventure.

The EDEN “#onlinetogether – Education in time of a pandemic”. webinars will be twinned on 2 June with the similar campaign of ICDE”#learningtogether” For this online event the topic: How to anticipate the global future educational landscape after the pandemic was choosen. UNESCO reported in May that about 75% of pupils and students cannot attend F2F classes. Fully online education on a global scale is unprecedented in history. Today we are talking about the “new normal” and “future normal”. What it is going to look alike? In this panel, distinguished speakers will reflect on and share their insights into the present situation in education.

Moderator: Mark Brown
Presenters: Sandra Kučina Softić, Antonio Teixeira, Neil Fassina, Mpine Makoe
