An open flask contains .200 mol of air. Atmospheric pressure is 745 mm hg and room temperature is 68 degrees Fahrenheit. How many moles are present in the flask when the pressure is 1.10 ATM and the temperature is 33 degrees Celsius?
Determine the adiabatic flame temperature (C). Assume product temperatures of 1500K and 3000K, and then linearly interpolate.
If the pressure exerted by ozone, O3, in the stratosphere is 3.0 times 10^- 3 atm and the temperature is 254 K, how many ozone molecules are in a liter?
An equilibrium mixture at 225 degrees contains 0.14M NH3 and0.19 M H2 for the reaction of 3H2+N2=2. If the Kc at this temp is 1.0*102, what is the equilibrium concentration of N2
The 1H NMR indicates there are three non-equivalent types of hydrogen atoms in your final compound with peaks at ~ 7.30 (m), 4.30(s), and 3.90(s) ppm. The three non-equivalent types of hydrogen atoms are aromatic hydrogens, methylene hydrogens
