ASAP PLS Calculate AH® for the reaction C4H4(g) + 2H2(g) - C4H8(g), using the
following data: AH'combustion for C4H4(g) = -2341 kJ/mol
AH combustion for H2(g) = -286 kJ/
mol AH®combustion for C4H8(g) =
2755 kJ/mol *

Which produce would best increase the amount of heat energy that is actually gained by calorimeter b

May someone me with these science questions

16. why must the number of electrons lost equal the number of electrons gained in every redox reaction? use 3 – 4 sentences in your own words to address this question. 18. what type of radiation is emitted when chromium-51 decays into manganese-51? show the nuclear equation that leads you to this answer. 19. a radioactive nucleus alpha decays to yield a sodium-24 nucleus in 14.8 hours. what was the identity of the original nucleus? show the nuclear equation that leads you to this answer.
