Nitrosyl bromide decomposes according to the chemical equation below.
2NOBr(g) 2NO(g) + Br2(g)
1.00 atm of NOBr is sealed in a flask. At equilibrium, the partial pressure of NOBr is 0.82 atm. What is the equilibrium constant for the reaction?
Suppose buffer #1 is prepared using 40.0 mL 0.1 M HC3H5O3 and 60.0 mL 0.1 M C3H5O3- to give a final volume of 100.0 mL. What is the pH of this buffer
how many meters away is a cliff if an echo is heard one half second away? assume that sound ws traveled at 343 m/s on that day.
the final temperature of the cu? I tried to use Q=MS(delta)T and solve for the tinal temp instead of the change in temp but kept getting 45°c.
A block of aluminum with a volume of 98.5cm^3 absorbs 68.4J of heat. If its initial temperature was 31.9 degrees celsius, what is its final temperature
Identify the type of interactions involved in each of the following processes taking place during the dissolution of sodium chloride (NaCl) in water.
If none of the available reagents can be used for this purpose, then identify another reagent from the table that could be used. For each reagent you've identified, write down a balanced chemical equation for the reaction that occurs.
We did TLC and column chromatography separating methylene blue and fluorescein. The solvent contained mostly ethanol but also had NaOH, and this NaOH formed SiO- with the silica (the stationary phase), which is in competition with the solvent for ..
The normal range for the carbonyl of a ketone is 1715 cm -1 . Why does the carbonyl peak for cyclopentanone appear at 1750 cm -1. Ring Strain
If 8.19g KIO3 is dissolved in enough water to make 500.0mL of solution, what is the molarity of the potassium iodate Soution. the Molar mass of KIO3is 214g/mol
Calculate the mole fraction of octane in the vapor at the above temperature.
for which Kp=2.00 at 20 C. A mixture of NO(g) at a partial pressure of 1.50 atm and NO2(g) at a partial pressure of 0.50 atm is allowed to come to equilibrium in a sealed container maintained at 20 C.
A solution of 0.10 M sodium acetate is mixed with a solution of 0.10 M acetic acid (Ka = 1.8*10^-5). When equal volumes of the two solutions are mixed together the resulting mixed has a pH of:
