#1 when table sugar (sucrose), C12H22O11(s) is digested, it is broken down by reacting with water to produce two simple sugars, glucose and fructose, each with the formula C6H12O6(s). C12H22O11(s) + H2O(l) -----> C6H12O6(s) + C6H12O6(s) An experiment was performed, and the following data were obtained ;( 4marks) Run initial (sucrose) (mol/L) Rate (mol/(Ls)) 1 0.050 3.09x10^-5 2 0.100 6.17x10^-5 3 0.250 1.50x10^-4 #2 For the reaction A + B +2C --> ABC2, the following data were obtained: run (a)...
Calculate the freezing point of a solution that contains 68.4 g of sucrose (table sugar, 342 g/mol) in 300. g of water. One mole of sucrose is 342 g. Kf for H2O = 1.86°C/m.
Table sugar (sucrose) molecules can be enzymatically broken down
to produce fructose and dextrose (also called glucose). The
reaction can be written
The following procedure was followed to determine the sucrose
content of sweet potatoes. A 78.7-g sample of sweet potato was
reduced to juice, and the juice was collected in a beaker. The
jucing machine was washed 3x with 100 mL portions of sodium
phosphate buffer with 2-3 min between rnsings. The juice and
washings were poured into a...
