Protective sols are:

Which of the following ions is the most effective in the coagulation of an arsenious sulphide solution?

Small liquid droplets dispersed in another liquid is called:

The pressure of the gas was found to decrease from $720$ to $480 \mathrm{mm}$ of Hg. When $5 \mathrm{g}$ of the sample of activated charcoal was kept in a flask of one litre capacity maintained at $27°\mathrm{C}$. If the density of charcoal was at $1.25\mathrm{g}/$$\mathrm{mL}$. The volume of gas adsorbed per $\mathrm{gm}$ of charcoal at $480 \mathrm{mm}$ of $\mathrm{Hg}$ is:

Graph between $\log \mathrm{x}/\mathrm{m}$ and $\log \mathrm{p}$ is a straight line inclined at an angle of $45°.$ When pressure is $0.5 \mathrm{atm}$ and $\ln \mathrm{k}=0.693,$ the amount of solute adsorbed per $\mathrm{gm}$ of the adsorbent will be:

Liquid-liquid sol is known as:

The adsorption isotherm for a gas is given by the relation $\mathrm{x}=\mathrm{a} \mathrm{p}/\left(1+\mathrm{bp}\right)$, where $\mathrm{x}$ is moles of gas adsorbed per gram of the adsorbent, $\mathrm{p}$ is the pressure of the gas, and $\mathrm{a}$ and $\mathrm{b}$ are constants. Then, $\mathrm{x}$:

During the process of digestion, the proteins present in food materials are hydrolysed to amino acids. The two enzymes involved in the process:

Proteins$\stackrel{\mathrm{Enzyme} \left(\mathrm{A}\right)}{\to }$Polypeptides$\stackrel{\mathrm{Enzyme} \left(\mathrm{B}\right)}{\to }$Amino acids, are respectively
