A 18.0 L gas cylinder is filled with 6.00 moles of gas. The tank is stored at degrees celsius. What is the pressure in the tank?
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?
Write out steps necessary to make ch3o=cch2ch3 starting with ethyne and any other chemicals
A sample of gas with a volume of 750 mL exerts a pressure of 98 kPa at 30 c. what pressure will the sample exert when it is compressed to 250 mL and cooled to -25 degree celsius.
35.00ml of a .500 M HCl was mixed with 25.00ml of a .500 M NaOH. What is the pH of the solution after mixing?
What is the basic structure of phosphatidyl cholines and how do they work as emulsifiers? Why is there so much research interest in phosphatidyl cholines and similar compounds in heart research?
Calculate the pH of a buffer tht contains 0.60M ammonium chloride
During the Purification of Lactate Dehydrogenase (LDH) experiment, you will need 50ml of buffer A150. Buffer A150 is 30mM Tris (pH 8.8) and 150mM NaCl. Given 1L of 1.5M Tris and 500ml of 5M NaCl,
Calculate the resulting pH if 455 mL of 0.200 M HCl is mixed with 315 mL of 0.0850 M Ca(OH)2.
The same reactant decomposes with a half-life of 211 s when its initial concentration is 0.160 M. Determine the reaction order
Is there an easy way to get a quick and dirty comparative coefficient of friction for water vs a solution of sodium bicarbonate and water? I only have the most basic of chemistry skills. Is there a chart you could point me to?
Calculate the mass of sodium acetate that must be added to 500.0 mL of 0.200 M acetic acid to form a pH = 5.00 buffer solution.
For the 3 wood preservatives noted, would acidic vs. alkaline soil or water conditions cause more (or less) leaching or dissolution of these compounds. How do these compounds actually leach out of wood into the environment?
