Explain the difference between oxidation and digestion

No, nothing of the sort. Digestion entails NO oxidation. Chemically speaking, digestion is mostly hydrolysis: proteins to amino acids, carbohydrates to monosaccharides, etc. Oxidation has nothing to do with oxygen.

meaning: oxidisation occurs when an element is oxidised or losses electrons. major example: rusting of iron.

meaning: digestion is the break down of food molecules into nutrients which the body later uses for energy, development, cell repair, etc. major part of digestion occurs in small intestine and begins from mouth.

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.
