Question 3)What are called mineral acids. Also give it's examples.

Answer 1

1) Is it because the OHOH group next to COOHCOOH in carbonic acid donates electron density to the COO−COOX− by resonance, making it a stronger base, 
2)The bubbles in fizzy drinks are caused by carbon dioxide (CO2). Carbon dioxide is a colourless odourless gas that dissolves in water under pressure. The carbon dioxide forms a very weak carbonic acid, (H2C03) which causesthe tingly sensation on your tongue.
3)Mineral acids range from superacids(perchloric acid) to very weak (boric acid). Mineral acids tend to be very soluble in water and insoluble in organic solvents.
Examples are sulfuric acid ,nitric acid and hydrochloric acid
