In the case of a bomb calorie emitter, we have a constant volume system. So with a constant volume system, the internal energy which normally equals q minus p delta v. Since the change in volume is equivalent to zero, the change in internal energy of the system, it's just the heat transfer of the heat transfer of the system. So in this case we have our system mainly as 1.048g of a certain compound With a molar mass of 78 g promote. And we find that once we put this system into a bomb calorie meter, which has a massive H 20 of 945 g. And we know the heat capacity of H 20 Is 4.184 jewels program degrees Celsius. We find that the temperature change in the surroundings, which is the water and the calorie meter itself in this case Is equivalent to 32.69 to -23.64. And we find that the temperature changes 9.05, 2 degrees Celsius. Okay, so we also know that the calorie meter constant is 891 tools per degree Celsius. When we're doing the heating combustion process, we have to heat both the water and the accelerometer. So they are both technically at the same temperature. So we can find that the heat transferred is equivalent to The mass of H 20. The capacity of water times the change in temperature plus the calorie meter constant times the change in temperature of the surroundings. So this is for the surroundings by substituting our values in. Okay, and converting to kill jewels as a more convenient unit. In this case, We can find that the change in the heat of the surroundings is 43 .9 Killer Jewels and converting this to into the system, which is one of the system is negative heat transferred of the surroundings. This is equivalent to negative 43.9 killer jewels. So this is for Benzene. So in this case we can write this as since it's for a constant volume system, it's the change in internal energy. So this occurs for 1.048g of our substance so we can delight this out And we find that this is approximately negative 41.9 killer jewels. Program and now we can convert this into killing joules per mole. And for one mole of us, uh certain One more certain reaction occurring, we have 78gg of our substance to negative 41.9 times 78 is equivalent to negative 3268 killer jewels promote. So here and I forgot to write out the combustion reaction. So we're combusting benzene. So this involves auction so we need to balance our reaction accordingly. So since we find the coefficient of auctions out here, we have to double the concentration of all our components, an auction is in excess here, so we really don't have to consider it in terms of our bomb calorie meter system, This becomes 12 co two plus six H 20. And we can find that the told the number of auction atoms is 24-plus 6, which is 30. So this is plus 15 auction atoms. And let me rewrite that. So this becomes plus 15 oxygen yields 12. c. or six h 12 groups. And this is the chemical reaction for what is occurring within the bomb columns. And that's it.
