A cylinder with a moveable piston contains 92g of Nitrogen. The external pressure is constant at 1.00 atm. The initial temperature is 200K.
When the temperature is increased by 59 K, by taking it out of the freezer, the volume will increase, according to the Ideal Gas Law.
Calculate the work for this process.
Express your answer in J.
The conversion factor between liter atmospheres and joules is 101.3 J = 1 L atm. The gas constant is 0.08206 (L atm)/(mol K). Molecular weight of Nitrogen is 28 g/mol
The pH of human muscle fluids is 6.8. Calculate the value of H3O+ in muscle fluid at 25 degrees Celcius. The answer should be in scientific notation.
The complex formed between Cu(I) and 1,10 phenanthroline has a molar absorptivity of 7000 L cm-1 mol-1 at 435 nm, the wavelength of maximum absorption.
Calculate the concentration of C6H5NH3+ in this buffer solution b) Calculate the pH after 4.0 g of NaOH(s) is added to 1.0 L of this solution (neglect volume changes)
The use of phenols such as tert-butylcatechol as free-radical scavengers is based on the fact that phenolic hydrogens are readily abstracted by radicals
What is the order of the reaction with respect to sucrose and the value of the rate constant k
Describe a circumstance in which it seems that lying might make more people happy than telling the truth. Would lying be the right thing to do in that circumstance, or is it our moral duty to tell the truth, even then? Consider what Immanuel Kan..
An equilibrium mixture of this reaction at a certain temperature was found to have [NH3]= 0.270M and [H2S]= 0.360M. What is the value of the equilibrium constant (Kc) at this temperature?

What volume of O2 is needed to react completely with 20.9L of H2 to give H2O if all gases are measured at 25 degrees C and 1atm? The Balanced equation is: 2H2+O2 ----> 2H2O
What I want to make sure is that Be(OH)2 is not a strong base right? reading a statement off of my chemistry book that "the principal strong base are the hydroxides of group IA elements and group IIA elements (except Be)." I also read that the giv..
