Calculate the number of kilojoules to warm 125 g of iron from 23.5°c to 78.0°c. a. 3.08 kj b. 0.736 kj c. 4.41 kj d. 3.08 × 103 kj

chemistry sucks a**

explanation:

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
