Question

give example of neutral oxide and and acidic oxide made from the same element in 2 marks question answer​

Answer 1

Answer:

Explanation:

Give examples of oxides that are neutral and acidic oxide.

Oxides of elements placed in the centre of the periodic table are amphoteric or neutral (e.g. CO, NO, N2O).SiO2 is slightly acidic.

Types of oxides

Acidic oxide: Oxides of non-metals.

Example : SO2,CO2,SO3

Basic oxides: These are oxides of metals

CaO, MgO, Na2O

Amphoteric oxides: Oxides shows both basic and acidic properties.

Example: ZnO, Al2O3

Neutral oxides: Shows neither acidic nor basic properties

Example; N2O, NO, CO

Answer 2

Answer:

Some compounds react with oxygen to form oxides which do not exhibit acidic nor basic characteristics. Such compounds are called as neutral compounds of oxygen.

Example: NO, CO.

Explanation:

Non-metals react with oxygen to form acidic compounds of oxides which are held together by covalent bonds. These compounds can also be called as acid anhydrides. Acid anhydrides usually have a low melting and boiling point except for compounds like B2O3 and SiO2 which have high melting points and form giant molecules.

Examples: NO, CO2

SO3 + H2O → H2SO4

B2O3 + H2O → 2H3BO3
