Notes On Gaseous State (BSc and Integrated Standard For all Concerned Entrance Examination)

 Notes On Gaseous State      This page provides you all details about the gaseous state of BSc standard. Concerned problems will be solved at the end of each concept. Continue till the end to find the easiest explanation of every concept you need in this regard . Postulates of Kinetic Theory of Gases: 1. All gas consist of a very large number of minute particles, called molecules.  2. The gas molecules are extremely small in size and are separated by large distance. The actual volume of the gas molecules is thus negligible as compared to the total volume occupied by the gas.  3. The pressure exerted by the gas is due to the bombardment of the molecules on the walls of the vessel.  4. The gas molecules collide with one another and also with the walls of the vessels. These collisions are perfectly elastic and there is no loss of energy during these collisions.  5. The distance between the gas molecules are very large. Thus, there is no effective force of attraction or r

Hidden Science: Rural Indian Mothers and Chemistry

 Rural Indian Mothers - They don't preach rather apply chemistry Rural Indian mothers possess a stock of practical knowledge about chemistry, often learned through generations of experience and necessity rather than formal education. This knowledge is deeply embedded in their daily lives, influencing their cooking, cleaning, healthcare practices, and agricultural activities. Read till the end to get the hidden talent and don’t forget to mention your mother in the comment section below. Here’s a glimpse into the chemistry that typical rural mothers in India engage with every day. Cooking: The Heart of the Household Cooking is where rural Indian mothers exhibit their profound understanding of chemistry. They know which ingredients to combine to bring out the best flavors and textures, often through intricate chemical reactions.       Me as an author of this article remeber those golden school days. When school time approached, I used to get angry with my mother knowing that coock

Calculation of change in oxidation number in a redox reaction

How to calculate the change in oxidation number in a redox reaction? Following are the steps to follow when you calculate change in oxidation number in a redox reaction. Once you practice two to three times than that becomes super easy to calculate the change in O.N. Take an example of the following reaction (First and easy method). H 2 S + Br 2  -----> HBr + S Step 1: Write the equation in the ionic form and do not balance it. H + +S 2- + Br 2  -----> H + +Br - +S Step 2: Ignore common ions on both side S 2- + Br 2  -----> Br - + S Step 3: Write the O.N of elements at the top now S 2- + Br 2 0  -----> Br - + S 0 Step 4: Find the O.N change of any element by: For example, O.N change of S = [0 – (--2)] X 1 = +2 O.N change of Br = [–1 – 0] X 2 = –2                             

Are you living in a country consuming maximum Toxins in Food?

 List of Countries Consuming Maximum and Minimum Toxins in Food Eating habits and the consumption of toxins can vary widely among different countries and cultures. Some countries and cultures may have diets that are higher in toxins due to factors such as food processing methods, agricultural practices, and dietary choices. Humans can consume some common types of toxins found in food which include: Pesticide Residues: Chemicals used to kill pests on crops can sometimes remain as residues on fruits, vegetables, and grains, which can be consumed by humans. Heavy Metals: Contaminants like lead, mercury, cadmium, and arsenic can enter the food chain through water, soil, and industrial pollution. Seafood, especially large fish, can sometimes contain elevated levels of mercury. Mycotoxins: These are toxins produced by certain fungi that can grow on crops like grains, nuts, and spices, especially under conditions of poor storage and high humidity. Examples include aflatoxins and ochr
