In the first step of glycolysis, the given two reactions are coupled. reaction 1: glucose + p i ⟶ glucose - 6 - phosphate + h 2 o δ g = + 13.8 k j / mol reaction 2: atp + h 2 o ⟶ adp + p i δ g = − 30.5 k j / mol answer the four questions about the first step of glycolysis. is reaction 1 spontaneous or nonspontaneous?

Asolution is made by dissolving 25.5 grams of glucose (c6h12o6) in 398 grams of water. what is the freezing point depression of the solvent if the freezing point constant is -1.86 °c/m? show all of the work needed to solve this problem.

An observation that requires measurement is called quantitative observable or qualitative
