Question

Use data from Table 7.2 to calculate the volume of butane, C4H10(g), measured at 20.1°C and 753 mmHg, that must be burned to liberate 4.95 104 kJ of heat.

delta Hf of C4H10 = -125.6 kJ/mol

Answer 1

You need 4.95x10^4 Kj and each mole of C4H10 provides 1.26x10^2 Kj. So you find the moles of butane. From pV=nRT, you can calculate the volume.

Answer 2

hi sweetie, there are demons everywhere, no rely the place we bypass, or what we do. i attempt to help people, clarify to them the fact, or maybe instruct individuals that witnesses are no longer what they have been instructed. I make errors each and on a daily basis, yet I do try no longer common to instruct that Jehovah's people do have love for one yet another. additionally, the apostates, nicely, sweetie, who's attentive to, perhaps they are going to come returned to Jehovah, basically He is attentive to the middle. sturdy question and have a great day.
