If 508 nm is directly related to the d-orbital splitting Fe2+ o-phen complex, explain how this wavelength would change (become higher, lower, or stay the same) if we changed the reaction from using Fe2+ to Fe3+. Explain why the wavelength change occurs.
From these data, and assuming that air obeys Charles's law, determine a value for the absolute zero of temperature in degrees Celsius.
Give the reaction scheme, showing the products formed (before hydrolysis), when one equivalent of ethylmagnesium bromide is treated with one equivalent of 5-hydroxy-2-pentanone
Rank the following in order of decreasing number of atoms
what is ture when equal masses of a and b are reacted?
When CO(g) (9.035 mol) and 144.6 grams of O2(g) in a 220.0 L reaction vessel at 608.0 °C are allowed to come to equilibrium the mixture contains 0.02021 mol/L of CO2(g). What is the concentration (mol/L) of CO(g)? 2CO(g)+O2(g) = 2CO2(g)
alculate the volume of .7000 M NaOH required to convert all of the phosphoric acid to sodium dihydrogen phosphate. What is the concentration of the sodium dihydrogen phosphate in the final solution
question why would you expect the heats of neutralization for hcl and nacl reaction and a hno3 and koh reaction to be
A mixture of ammonium chloride and sand is placed in an evaporating dish and massed at 56.246g. The mixture is heated, driving off the ammonium chloride and massed again
If the initial volume of the container, before any reaction takes place, is 5.70 L, determine the volume of the container after the N2 (g) and H2 (g) have reacted to completion.
Problem- A buffer is created by combining 150.0mL of 0.25M HCHO2 with 80.0mL of 0.25M NaOH. What is the pH
Calculate the minimum number of grams of propane,C3H8 (g) , that must be combusted to provide the energy necessary to convert 3.15kg of ice at -15.5degC to liquid water at 75.5degC. C3H8 (g)
How does the addition of aqueous NH3 to a solution separate and identify Cu2 and Bi3 ions? Why wouldn't the additon of a strong base, such as KOH, work just as well as the addition of aqueous NH3?
