$\huge\boxed{\underline{\mathbb{\red{A}\green{n}\pink{S}\orange{w}\blue{E}\pink{r:-}}}}$

Reaction Of Metal With Water

They react with water to form alkalis such as sodium hydroxide and potassium hydroxide. ... They form their respective oxides when reacted with hot water. Mg + H2O → MgO + H2. Iron is less reactive than sodium, potassium, calcium, zinc and magnesium.

Air

Generally, metals are malleable and ductile. ... On burning, metals react with oxygen to produce metal oxides which are basic in nature. Non-metals react with oxygen to produce non- metallic oxides which are acidic in nature. Some metals react with water to produce metal hydroxides and hydrogen gas.

Acid

If metals react with acid it will produce salt with water and if it will react water then it will produce salt and hydrogen, when it react with air it will produce oxides. If non-metal react with acid it will also produce salt and water and if react with water it will produce only salt

base

Some metals react with a base to form salts and hydrogen gas. ... All the metals do not react with bases to form salt and hydrogen. Reaction of non-metal with a base. Some non-metals react with bases but no hydrogen gas is produced.

displacement reaction

A displacement reaction is the one wherein the atom or a set of atoms is displaced by another atom in a molecule. For instance, when iron is added to a copper sulphate solution, it displaces the copper metal. The above equation exists when A is more reactive than B.
