How do you rationalize the ordering of the following pairs in the spectrochemical series?
a) I- < Cl-b) OH- < H2Oc) SCN- < CN-
substance a and b are the same mass and at the same initial temperature. When the same amount of heat is added to each the final temperature of a is 75 degrees celsius
Find the concentration of Ca2+ and IO-3 in a saturated Ca(IO3)2 solution prepared by adding Ca(IO3)2 to a 0.015 M solution of KIO3
In a beaker of boiling water, there are many bubbles forming throughout the liquid. What gas comprises the bubbles?
What wavelength (in s-1) of light would be required to change the vibrational number from n=0 to n=4, assuming O-H acts as a harmonic oscillator?
when 142 grams of calcium flouride are reacted with an excess of sodium bromide, calculate the mass of calcium bromide formed.
A 643 mL gas sample at STP is compressed to a volume of 285 mL, and the temperature is increased to 26C. What is the new pressure of the gas in Pa? Answer in units of Pa.
Many common weak bases are derivatives of NH3, where one or more of the hydrogen atoms have been replaced by another substituent.
A chemist prepares a sample of hydrogen bromide and finds that it occupies 258 mL at 60 degrees celsisus and 476 Torr. What volume would it occupy at 0 degrees celsisus at the same pressure? Answer in units of mL to 5 decimal places.
If you wanted to prepare a solution of CO in water at 25 degrees Celsius in which the CO concentration was 2.5 mM, what pressure of CO would you need to use?
A tank initially at a pressure of 6.70 atm contains 2.0 moles of oxygen gas at 25.0 degrees celsius. Its temperature is then increased to 45.0 degrees celsius
What mass (in grams) of solid sucrose (C12H22O11) would need to be added to 2000 grams of water to make an ideal solution with a boiling point of 102.9°C? (Kb for water is 0.512°C/m)
When preparing the solutions for Part A, an aqueous solution of diamine and NaOH is made. Why isn't a solution of NaOH and diacid chloride in cyclohexane made
