The answer is a) K and CrO4 only.
<span>1.23x10^24 atoms/6.022x10^23 atom/mol = 2.04 mol H20 </span>
The change in internal energy of the combustion of biphenyl in Kj is calculated as follows
=heat capacity of bomb calorimeter x delta T where delta T is change in temperature
delta T = 29.4 -25.8= 3.6 c
= 5.86 kj/c x 3.6 c = 21.096 kj
