Does a reaction with a delta H of 14kj/mol and a delta S of 150 J/molK at 298K favor reactants or products?
Starting from 1-methylcyclopentene and using other reagents and number of steps that you need, synthesize the following compounds.
The reaction OH(aq) + HCN(aq) H2O(l) + CN(aq) is first-order in both the OH and HCN concentrations. The rate constant at 25oC is 3.7×10^9 mol^-1 L s^-1. In an experiment, 0.500 L of 0.020 mol L ^-1 NaOH(aq) is rapidly mixed with an equal volume of..
What is the chemical formula of a homonuclear diatomic gas if it has a pressure of 1.40 atm and a density of 1.82 g/L at 27 ºC?
Explain briefly why CuSO4 is more soluble in water than in organic (nonpolar) solvent.
Calculate the concentration of sodium ion in a solution made by diluting 350.0 mL of 3.00 M sodium carbonate to a total volume of 2.00 L.
Calculate the volume of a .850 M KOH solution necessary to neutralize 25.00 mL of 1.500 M solutions
Chromatographic column, it is important to let the level drop in the column eluent to the level of the sand before applying the solution of the compound to be separated. What effect would have on the efficiency of separation ignore this recommenda..
Lead and iron are common alloying elements found in brass. Would the presence of these elements complicate the analysis of brass
What is the concentration of H+ in 0.0025 M HNO3? What is the pH of this solution? What is the OH- concentration in this solution
Sulfur trioxide dissolve in water, producing H2SO4. How much sulfuric acid can be produced from 13.5 mL of water and 26.1g of SO3?
Ionization energy is the energy needed to eject an electron from an atom. Compute the ionization energy of a hydrogen atom in its first excited state (n = 2).
In this experiment the choice of precipating reagent is important. briefly explain what the consequences would be if excess 6M NaOH solution instead of 6M NH3 solution were used to seperate Fe3+ and Al3+ ions from Ca2+, Cu2+, and K+ions at pH9-10...
