Question

chemical properties of metal and non metals​

Answer 1

the case of the physical properties of metals and nonmetals differ in their ability to chemical the combined with other elements and compounds reaction with oxygen oxygen reacts with metal and nonmetals to produce oxide reaction with water metal reacts with water to form oxide or hydroxide and hydrogen reaction with acid let us observe how dilute acid react with metal and nonmetal take an example of following metals and nonmetals magnesium ribbon aluminium fall iron filling copper wire charcoal powder sulphur powder keep the samples in separate test tubes to each test tube add about 5 ml of dilute hydrochloric acid not if a reaction occurs if if it does bring a burning matchstick to the mouth of the test tube what happens if a reaction is not eka eka heat the test tube does a reaction occur now test with the lighted matchstick now try the same with dilute sulphuric acid instead of hydrochloric acid which metal and nonmetals did not react with dilute acid at all reaction with bases only some metals such as aluminium zinc and lead accept from with strong bases such as sodium hydroxide to release hydrogen gas that reaction of non metals with sodium hydroxide is complex
