Nonmetal oxides are known as acidic oxides because they dissolve in water forming acidic solutions, we can use water to differentiate between calcium and zinc because calcium can react with cold water, while zinc...
Salts formation methods Salts can be practically prepared by Reaction of active metals with diluted acids , Reaction of metal oxides with acids , Reaction of metal hydroxides with acids and Reaction of metal...
The substitution reactions are the reactions that depend on the activity of metals, where the element which is more active substitutes (replaces) the less active one in another compound, The activity of metals can...
The metals Metals are the elements that have less than four electrons in their outermost energy levels, During the chemical reactions, the atoms of the metallic elements tend to lose their outermost electrons, and...
