Passive diffusion is a form of passive transport and a type of diffusion by which particles from a high concentration gradient passes through a biological membrane to a low concentration gradient. Diffusion, or simple diffusion on the other hand, is the passage of molecules without the need of a membrane.
Answer: Your guess is right
Explanation: Other reactions release energy, so forming sucrose from glucose and fructose is endoergic. Also a water molecule is formed.
When two molecules form new molecule, order is increased and energy is needed that. IT could also possible to use standard energies of formation.
A change in the color of a substance -- this one is indeed a chemical change. Think of iron, if iron turns reddish, it's a completely different substance.
