Answer:
Alkalai metals are strong bases capable of neutralizing acids when they react with water.
Explanation:
b) Malleability:- The ability of metals to turn into thin sheets .
c) Ductility: The ability of a metal to receive permanent deformation without fracturing.
d) Aqueous solution:-a solution in which the solvent is water
Answer:
(a) . Alkali : A chemical substance that reacts with acid to form a salt. An alkali has a pH value of more than 7 .
(b) . Malleability : the quality or state of being malleable: such as. a : capability of being shaped or extended by hammering, forging, etc. the malleability of tin. b : capability of being influenced or altered by external forces The malleability of memory .
(c) . Ductility: is the ability of a material to be drawn or plastically deformed without fracture. It is therefore an indication of how 'soft' or malleable the material is. The ductility of steels varies depending on the types and levels of alloying elements present.
(d) . Aqueous solution : An aqueous solution is a solution in which the solvent is water. It is mostly shown in chemical equations by appending to the relevant chemical formula. For example, a solution of table salt, or sodium chloride, in water would be represented as Na+ + Cl− .
