Question

after going through the activity 3.10 mention the reactions of metals and non metals with oxygen , acid and also metals with non metals​ "class 10" and if u don't have that activity just see in google and answer meeeeeee​

Answer 1

Metals

• with oxygen

metals reacts with oxygen to form basic oxides which dissolve in water to form alkali

e.g 2Ca + O2 ------ 2CaO

• with acid

metals above hydrogen react with acid to liberate hydrogen gas

Zn + 2HCl ----- ZnCl2 + H2

Answer 2

metal and non metal react with oxygen to form respective oxides but non metal oxides are acidic whereas metal oxides are basic in nature


For acids

Non-metals react with oxygen to produce non- metallic oxides which are acidic in nature. ... Metals react with acids and produce metal salts and hydrogen gas. Generally, non-metals do not react with acids. Some metals react with bases to produce hydrogen gas.

Mg +HCl = MgCl2 + H2
