Question

most of the metals react with oxyzen and form_____​

Answer 1

most of the metals react with oxyzen and form metal oxides

metal oxides are basic in nature

Answer 2

$\mathfrak{\huge{\underline{Answer:}}}$

$\textbf{\underline{\underline{Reaction\:With\:Oxygen :}}}$

To check whether what happens when metals react with oxygen, Let's do an activity :

Hold a magnesium ribbon with a pair of tongs and ignite it. Magnesium ribbon burns with a bright white light and forms a white powder. The powder formed is Magnesium Oxide.

$\sf \: 2Mg(s) + O2(g) \implies 2MgO(s)$

$\sf \: Magnesium + Oxygen \implies \: Magnesium \: Oxide$

Collect the Product and mix it in water. Dip a stripe of Red Litmus Paper in the solution. We will observe The Red Litmus Paper turns into Blue, indicating this is an Alkaline Solution.

$\sf \: MgO(s) + H20 (l) \implies Mg(OH)2$

$\sf \: Magnesium \: Oxide + W ater \implies Magnesium hydroxide$

This activity shows that Metals react with oxygen to form Metallic Oxides which are Basic in nature.
