S Block Elements (Alkali and Alkaline earth Metals) and Hydrogen

Chemistry, Class 11, Group 1: Alkali metals, NEET, The s-Block Elements

Introduction If the periodic table were a city, the s-block would be a small neighbourhood full with structures and properties that are strikingly similar to one another. The s-block is located at the far left of the periodic table and contains all of the elements found in the first two columns (columns 1 and 2), […]

Knowing More on Uses Of Phosphorus

Chemistry, Class 11, Group 1: Alkali metals, NEET, The s-Block Elements

Phosphorus is not found as a free element in nature, although it can be found in a variety of minerals, including gold. In commercial production, it is made from calcium phosphate (phosphate rock) through the following process: calcium phosphate is heated in a furnace with silica and carbon to produce vaporized tetraphosphorus, which is then

Characteristic Difference Between D and F Block Elements

Chemistry, Class 11, Group 1: Alkali metals, NEET, The s-Block Elements

It is contained within the d-block of the periodic table, which includes groups 3 through 12. D-block elements are the elements that are placed in the third through twelfth groups. The d-orbitals of these elements are gradually filled in as the periods of the elements increase. The f-block elements have been placed at the bottom

Distribution of Water in the Universe

Chemistry, Class 11, Hydrogen, NEET, Water, hydrogen peroxide

The majority of the water in Earth’s atmosphere and crust is saltwater, seawater, with fresh water accounting for less than 1% of the total. The great majority of water on Earth is saline or salt water, with an average salinity of 35 (or 3.5 percent, or around 34gm of salts in 1 kg of saltwater),

Fuel cell and corrosion

Chemistry, Class 11, Hydrogen, NEET, Water, hydrogen peroxide

INTRODUCTION A fuel cell can be thought of as an electrochemical cell that generates electrical energy from fuel through the use of an electrochemical reaction. These cells require a constant supply of fuel as well as the presence of an oxidising agent in order to maintain the reactions that generate electricity (generally oxygen). As a

Hydration Reactions: H2o

Chemistry, Class 11, Hydrogen, NEET, Water, hydrogen peroxide

A hydration reaction is a chemical process in organic chemistry in which a hydroxyl group (OH-) and a hydrogen cation (an acidic proton) are added to the two carbon atoms bound together in the carbon-carbon double bond that forms an alkene functional group. The reaction is typically carried out in a highly acidic, aqueous solution.
