Q. Gold numbers of some colloids are :

Q. The fat, glyceryl trioleate, is metabolized via the following reaction. Given the enthaplies of formation, calculate the energy (kJ) liberated when 1.00 g of this fat reacts.
(Atomic weights : $C=12.01,H=1.008,O=16.00$).
$C_{57}{H}_{104}{O}_6\left(s\right)+80O_2\left(g\right)⟶57C{O}_2\left(g\right)+52H_{2}O\left(I\right)$
$\Delta H{C}_{57}{H}_{107}{O}_6=-70870kJ/mole$
$\Delta H{H}_{2}O\left(I\right)=-285.8kJ/mole$
$\Delta HC{O}_2\left(g\right)=-393.5kJ/mole$

Q. Gold number of some lyophilic sols are
$\begin{array}{cc}I.Casein& 0.01\\ II.Haemoglobin& 0.03\\ III.GumArabic& 0.15\\ IV.Sodiumoleate& 0.40\end{array}$
Which has maximum protective power?
