A catalyst is a substance which:

Pesticides & insecticides are available in the form of :

The catalyst in photosynthesis is:

Cleansing action of soaps includes:

Which metal is used as a catalyst in the hydrogenation of oils?

In physical adsorption, the adsorbent and adsorbate are held together by the:

The action of cleaning of oily dirt by soap is based on

Whenever a mixture of gases is allowed to come in contact with a particular adsorbent under the same conditions, the more strong adsorbate is adsorbed to greater extent irrespective of its amount present. For example, $$H_2O$$ is adsorbed to more extent on silica gel than $$N_2$$ and $$O_2$$. This shows that some adsorbates are preferentially adsorbed. It is also observed that preferentially adsorbable adsorbents can displace a weakly adsorbed substance from the surface of an adsorbent.

The metal used as a catalyst in the hydrogenation of oils is:

On adding dilute $$HCl$$ to chalk piece, $${CO}_{2}$$ is evolved. This is an example of:
