‘X’ is a protecting colloid. The following data is obtained for preventing the coagulation of 10 mL of gold sol to which 1 mL of 10% NaCl is added. What is the gold number of ‘X’?
Which sol is used as an intramuscular injection?

Which of the following reactions give phosphine? i. Reaction of calcium phosphide with waterii. Heating white phosphorus with concentrated NaOH solution in an inert atmosphereiii. Heating red phosphorus with alkali
Consider the reactions:
Consider the following reactions: Y and Z respectively are:
The incorrect statement about 'B' is:
The conversion of X to Y is:
At STP \(x\) g of a metal hydrogen carbonate (MHCO$_3$) (molar mass \(84 \, {g/mol}\)) on heating gives CO$_2$, which can completely react with \(0.02 \, {moles}\) of MOH (molar mass \(40 \, {g/mol}\)) to give MHCO$_3$. The value of \(x\) is:
What is the kinetic energy (in \( {J/mol} \)) of one mole of an ideal gas (molar mass = \(0.01 \, {kg/mol}\)) if its rms velocity is \(4 \times 10^2 \, {m/s}\)?
