Based on the number of chiral centers in Morphine, determine the maximum number of stereoisomers that are theoretically possible: show calculations
A sample of an unknown compound was analyzed and found to contain 19.97% phosphorus and oxygen - what is the empirical formula of the compound
The intramitochondrial concentration of malate under some conditions is 0.22 mM and the NAD+/NADH ratio is 20. Calculate the maximum intramitochondrial concentration of oxaloacetate under these conditions
We need to make a 4% NaOH solution in ethanol. How much NaOH do we add to 50.0 mL of ethanol to make a 4% NaOH solution. Density of Ethanol=0.789 g/mL molar mass= 46.06844 g/mol and NaOH molar mass= 39.997 g/mol.
A year later a single large crystal of mass 50 g is at the bottom of the flask. Explain how this experiment provides evidence for a dynamic equilibrium between the saturated solution and the undissolved solute.
130 mL of an HCl solution with pH of 3.90 is added to 200 mL of an HNO3 solution. The resulting solution is 1.40 mL. What was the pH of the original HNO3 solution?
The Environmental Protection Agency has estimated that 119 tons of mercury are currently emitted to Earth's atmosphere annually due to human activities
An unknown gas effuses at a rate of 86.6 mol/hr. Under similar conditions, I2 effuses at a rate of 30.4 mol/hr. What is the molar mass of the compound.
Why is it not possible to convert bromobenzene to benzoic acid by the nitrile method and how could this conversion
An unknown metal hypochlorite salt, M(ClO)2, is subjected to analysis by iodometric titration: the salt is dissolved in dilute sulfuric acid, treated with excess aqueous KI, and then titrated with Na2S2O2 in the same manner as in your experiment
Pyridine is a heterocyclic aromatic compound similar in structure to benzene. It is widely used as an organic base because it reacts with acids, but is inert to most reagents.Write an equation with structural formulas to show how pyridine reacts w..
magnetite was found to contain 2.5698 g of iron and 0.9816 g oxygen. What is the empirical formula for this oxide of iron?
These electrons cause the emissions of secondary electrons-called auger electrons-from the metal surface. The kinetic energy of the auger electrons depends on the composition of the surface
