plz help me in this question
plz give me in short answer plz I request you plz......
Answers
Explanation:
metals are sonorous, ductile,mealible, and good conductors of heat and electricity
Non metals r not sonorous, non ductile and are bad conduct of heat and electricity
Answer:
1.metals are ductile,malleable,sonorous,hard and lustrous
non-metals are non-ductile,non-malleable,non-sonorous,non-lustrous and brittle
2.when they react they form metal oxides and non metal oxides. metal oxides are basic compounds while non-metal oxides are acidic compounds.
3.a. copper is less reactive than zinc so it is unable to displace zinc
b.metals are good conductors of electricity and can conduct electricity.
c.phosphorus is highly reactive with air (basically oxygen) so it is stored under water.
4. metals react with oxygen to form metal oxide while non-metal react with oxygen to form non-metal oxides
metals react with water to form metal hydroxide and release hydrogen gas while non-metals do not react with water
metals react with acids to form salt and hydrogen gas while non metals do not react with acids.
metals react with acids to form salt and hydrogen gas while non-metals react to form salts and water.
5. Metals are used to make cooking vessels and electric cables.
Chlorine, a non-metal is used for purification of water.
Diamond, gold and silver are used in jewelry.
Zinc is used to galvanise iron.
Iron is used to make cars, buses, trucks etc.
