Between a lump of charcoal and charcoal powder of same mass which is a better adsorbent ?

Between sodium hydrogen carbonate and magnesium hydroxide, which is a better antacid and why?

The amount of gas adsorbed physically on charcoal increases with :

Why activated charcoal is a better absorbent than ordinary charcoal ?

One gram of charcoal adsorbs 100 mL of 0.5 M -acetic acid to form a monolayer and the molarity of acetic acid reduces to 0.49. Calculate the surface area of charcoal adsorbed by each molecule of acetic acid. The surface area of charcoal is 3.01xx 10^2 m^2 g^(-1) .

Between CO and C , which is better reducing agent at 983 k
