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 *

it is the most commonly accepted one

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.

12 is it do you think so
