explain the mechanism of digestion of carbohydrates, proteins, fats, vitamins and minerals separately in human body. state the body parts involved in the digestion and the impact on the nutrient.
Digestion of proteins begins in stomach. The gastric juice contains HCl, which causes denaturation of proteins, and pepsin, that breaks down proteins into smaller peptides. Then, in the small intestine...

Calculate the molarity of the NaCl NaCl solution when 14.6 g g of NaCl NaCl is dissolved in 100 mL mL of water.
Molar mass of NaCl= 58.4414.6/58.44=0.25mol0.25/0.1= 2.5mol/L

Calculate the vapor pressure of salt solution containing 20 grams salt (NaCl) in 1.5 kg of water at 25°C? Note: P° water at 25°C is at 24 torr and molecular weight of NaCl is 58g/mol
Pa=XPa° = 83.3333 x 23.8/83,6751333= 23,7027806 torr.

Calculate the mass of salt (NaCl) that is expected to be made based upon the mass of NaHCO3 used. This is called the 'theoretical mass of NaCl'.
M(NaCl) = 23+35.5 = 58.5 g/molM(NaHCO3) = 23+1+12+16*3 = 84 g/molAs NaCl and NaHCO3 have the same amount of Na, theoretical mass of NaCl will be:m(NaCl, theor) = m(NaHCO3)/M(NaHCO3)*M(NaCl) =...

Can salt be lost during evaporation because after evaporating H20 from NaCl i was left with 0.1g of salt but using the equation m=n×M there should of been 0.1255g of salt. How was the salt lost?
Sodium chloride is not decomposed when heated in water and you could not lose it that way. It is lost due to experimental error (maybe spillage of the solution)
