Explain the order of elution you observed while performing the gas chromatography for this experiment. What property of the product molecules seems most important in determining relative retention times?
HClO is a weak acid (Ka = 4.0 × 10-8) and so the salt NaClO acts as a weak base. What is the pH of a solution that is 0.077 M in NaClO?
Calculate the cell potential for the following reaction as written at 61 °C, given that [Cr2 ] = 0.826 M and [Ni2 ] = 0.0200 M. Cr(s) + Ni ^2+ (aq) --> Cr^2+ (aq) + Ni(s)
determine the pressure in a 125-L tank containing 56.2 kg of oxygen gas at 21.0 oC
When atoomic orbitals are hybirdized the s orbital and at least one p orbital are always hybirdized. III. to create tetrahedral structures the s orbital and all three p orbitals must be hybirdized.
What are the economics of manufacturing a drug either as a racemic mixture or in its biologically active form?
The half-cell is a chamber in the voltaic cell where one half-cell is the site of an oxidation reaction and the other half-cell is the site of a reduction reaction.
What is the molarity of the carbonate ion in sodium carbonate, Na2CO3, prepared by dissolving 3.5 g of sodium carbonate in enough water to form 0.800 L of solution?
Why does the water solubility of the acidic compound change when going from the aqueous base to the aqueous acid? pls write the eq'n to illustrate this change.
a.) Available Electrons (AE) b.) Needed Electrons (NE) c.) Geometry Description d.) Number of sigma bonds e.) bonding description f.) lewis dot structure
Calculate the standard emf for each of the following reactions:a)H2(g) + F2(g)---> 2H+(aq) + 2F-(aq)
A gaseous fuel mixture stored at 752 mmHg and 298 K contains only methane and propane . When 11.6L of this fuel mixture is burned, it produces 767kJ of heat methane : 890 kJ/mol propane : 2,220 kJ/mol
Define Ideal gas law, Calculate the free energy of mixing when 1 mole of liquid A is mixed with 4 moles of liquid B at 25 degrees C to form an ideal solution. What is the change in chemical potential of component A?
