Problem- The prosthetic group on sphingolipids can be: A. amino acids B. a peptide C. carbohydrates D. a heme group E. zinc
Elucidate the each and every step in detail for helping me to understand the answer of the above problem
When a certain liquid of molar mass 46.1 g/mol freezes at -3.65 degrees celsius its density changes from 0.789 g/cm^3 to 0.801 g/cm^3. Its enthalpy of fusion is 8.68 kJ/mol. Estimate the freezing point of the liquid at 100 MPa
If 30 mL of 6.2 M H2SO4 was spilled, what is the minimum mass of NaHCO3 that must be added to the spill to neutralize the acid?
consider the dissolution of mns in water ksp 3.0 times 10-14.mnss h2ol mn2aq hs-aq oh-aqhow is the solubility of
For combustion of hydrogen gas the standard enthalpy of reaction is -286 kJ/mol and the standard Gibbs free energy of reaction is -237 kJ/mol at 298 K and 1 bar.
1.00 mol Zn reacts with excess hydrochloric acid, 1.00 mol H2 gas is produced. At 25ºC and 1.00 atm= 101,325 Pa, this amount of H2 occupies 24.5 L (= 24.5 x10-3 m3). How much work is done by the chemical system.

Consider the decomposition of calcium carbonate. Assume that ?H° = 177.8 kJ/mol and ?S° = 160.5 J/K·mol for the temperature range. CaCO3(s) -> CaO(s) + CO2(g)
Compare your predicted molecular polarity, and the dipole moment predicted by Alchemy, to the actual measured values in the given table. Which modeling system gave better results
What is the pOH of a solution that is prepared by mixing 25.0 mL of 0.200 M HNO3 and 25.0 mL of 0.150 M KOH
Three liquids of different densities are mixed. Because they are not miscible (do not form a homogeneous solution with one other), they form discrete layers, one on top of the other.
Limonene (MW 136) is a nice smelling liquid found in lemon and orange peels. The bp of limonene is 175, However it co-distills with water at 97.5. If the vapor pressure of water at 97.5 is 690 mm Hg, Explain what percentage of the steam-distillate..
