Step 2: Definition of Alkaline Earth MetalsThe term "alkaline earth metals" refers to the fact that these metals produce alkaline (basic) solutions when they react with water. The word "alkaline" comes from the Arabic word "al-qaly," which means "ashes of saltwort," and "earth" refers to...
Why alkali metals are normally kept in kerosene oil? Solution: Alkali metals are normally kept in kerosene oil becausein the air they are easily oxidized to oxides which may dissolve in the moisture of the air to form hydroxidesor they also combine directly with water vapours present in moistur...
A surprisingly large share of demand is tied to the need for food, water, and basic services such as schools, roads, and bus service. Poor people require these basics just as much as rich people do. There are literally billions of poor people in the world. If the wages ...
Soap is a mixture of fat or oil, water, and an alkali, or basic salt. The ancientBabyloniansare credited with being the first people to make soap. Their recipe for animal fats, wood ash and water has been found carved into clay containers dating back to 2800 B.C., according tosoaphis...
