Calculate AH® for the following: CH (8) + Ch() - CC1(0) + HC1) (unbalanced]
AH ICH (2) = -74.87 kJ/mol
AH CCl4(e)) = -96.0 kJ/mol
all ICCI(0) = -1.39 kJ/mol
AHHCUC)] = -92.31 kl/mol
AHHICK(04)) = -167.46 kJ/mol
SHICH2)) = 1210 kJ/mol

Given that 1 mi = 1760 yd, determine what conver- sion factor is appropriate to convert 1849 yd to miles; to convert 2.781 mi to yards.

Americium-241 undergoes fission to produce three neutrons per fission event. if a neutron-absorbing material is mixed in with this sample so that the rate of neutron production drops down to 1.8 neutrons per fission event, which will be effective at achieving a critical mass? check all that apply. remove a deflective shield surrounding the sample. remove absorbent material mixed in with the sample. compress the sample of americium-241.

Two metal blocks that have slightly different temperatures are placed next to one another. after five minutes, they both have lower but equal temperatures. according to the law of conservation of energy, what  most likelyhappened? energy was created inside the blocks.energy was destroyed inside the blocks.energy was absorbed into the blocks from outside the system.energy was transferred from the warmer block to the cooler block.
