Part C 2A-->B + C, given that [A]o=0.153 mol.L^-1, and that after 115 s the concentration of B rises to 0.034 mol*L^-1. In the solutions manual: [A]=(0.153 mol A/L)-[(2molA/1molB)*(0.034 mol B/L)]=0.085 (mol A)*L^-1 this probably has a simple answer, but why do we subtract the two? thanks in advance!

When plugging in the value for heat capacity of ice, why is 4.184 plugged in? Isn't that the heat capacity of h20 water?

13.11(d)

Pt(s) | O2(g) | H+ (aq) || OH-(aq) | O2 (g) | Pt (s)

In the solutions manual the end answer is
4H20(l)-->4H+(aq) + 4OH- (aq)

what happened to the O2?

Thank you in advance!

In the solutions manual, it tells us that 3 CRC bonds are formed. I understand C6H6 is in a ring structure, but what part of the structure is a CRC bond?

7.11: In a combustion cylinder, the total internal energy change produced from the burning of a fuel is -2573 kJ. The cooling system that surrounds the cylinder absorbs 947 kJ as heat. How much work can be done by the fuel in the cylinder? The solutions manual states that q=-947, making the end answ...

For [Pt(H20)4][Zn(OX)2]:

Would the name for this be all one word? Also, how would we determine the oxidation numbers for Pt and Zn?
