A student analyzes a sample which produces a positive Molisch Test followed by a negative Iodine/Potassium Iodide Test followed by a positive Benedict's Test followed by a positive Barfoed's Test followed by a positive Seliwanoff's Test followed by a positive Bial's Test. The sample is:

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.

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
