A.0.50 mole sample of N 2 O 4 (g) is allowed to come to equilibrium with NO 2 (g) in a 0.750L flask. At equilibrium , 0.42mol N 2 O 4 remains. Calculate the equilibrium concentrations of N 2 O 4 and NO 2 and calculate the equilibrium constant , K c for the reaction.

Only glucose goes through the entire glycolytic pathway (glycolysis). Explain how it is possible that we can get energy from the monosaccharides galactose and fructose. (08) every Common culture says too much sugar makes you fat. If carbohydrates and dietary fats are structurally different molecules, explain how eating too much sugar c could make
