A quantity of gas in a piston cylinder has a volume of 0.500 m3 and a pressure of 200 Pa. The piston compresses the gas to 0.150 m3 in an isothermal (constant-temperature) process. What is the final pressure of the gas?
Write an equation for any changes observed - Write an equation for the formation of any precipitate.
oxygen gas is collected over water at 25 degrees C. The total pressure of the gas is 780.00 mm Hg. What is the partial pressure of the dry oxygen gas?
State whether or not each of the following equilibrium reactions could have the equilibrium expression.
Metals Covalently Bonded to Benzene, Specifically interested to know why you don't see metals bonded to benzene with a covalent sigma bond. I am not interested in metal benzene complexes.
How does a catalyst chance the rate of reaction without affecting it's equilibrium?
Calculate the mass percent of a solution that is prepared by adding 70.9g of NaOH to 492g of H20 ... I read that the way to calculate this is Solute/solution x 100%
Low molecular weight esters have fruity flavors and odors. Explain why do carboxylic acids, which have lower molecular weights than esters of that carboxylic acid have higher boiling points lower vapor pressure and volatility than the correspond..
Why do you think the enthalpy of activation, H ‡ , for a syn-periplanar elimination is higher than that for an anti-periplanar elimination
a. What is the role of the Mg in preventing corrosion? b. What qualities must a metal like Mg have to prevent oxidation of another metal? c. Calculate the K for corrosion with Fe present. Assume standard conditions.
in addition to the main product what are two side reactions that could occur in the experiment of the diels-alder
An Erlenmeyer flask weighs 148.8 g when empty. When filled with water (d = 1.00 g/cm^3), the flask and its contents weigh 346.3 g.
If you used the method of initial rates to obtain the order for NO2, predict what reaction rates you would measure in the beginning of the reaction for initial concentrations of 0.200 M, 0.100 M, and 0.050 M NO2.
