Voyager 7 has obtained the composition of the atmosphere of Titan, Saturn's largest moon. The total pressure is 1220 mm Hg and the atmosphere consists of 82 mol percent nitrogen gas, 12 mol percent argon gas and 6.0 mol percent methane CH4. What is the partial pressure of each gas?
Question- One drop has a volume of about 0.05 mL, thus the concentration of Cu2+ in the dilute half-cell is about (0.05mL/25mL)(0.1M)=2x10^-14 M. use Nernest equation E=-(0.0592/n) log [An+ Mdil] / [An+ Mconc] to calculate it at 298K.
1.draw a diagram on the line below which shows 2.5 transverse waves. measure the line and calculate the wavelength of a
What is the conjuate base of HPO4^2- C. Which acid has the weaker conjugate base. D. which acid has the stronger conjuate base. E. which acid produces more ions
Calculate the percentage of He atoms at 100oC which have speeds in the range between 1200 m/s and 1300 m/s. Calculate the percentage of these He atoms that have speeds greater than 5000 m/s
An experiment requires 44.0 of ethylene glycol, a liquid whose density is 1.114 . Rather than weigh the sample on a balance, a chemist chooses to dispense the liquid using a graduated cylinder. What volume of the liquid should he use?
I understand that the height of a peak in NMR spectroscopy indicates the number of identical hydrogens in that particular group. But what does it mean when peak height is measured in non-H units lacking a common denominator
Show the chemical equation for this reaction. Explain FULLY why 2-methyl-2-hexene is the major product.
calculate the heat of neutralization from the following data . 200 ml of 1 M HCl is mixed with 400 ml of 0.5 M Na OH . The temperature rise in calori meter was found to be 4.4 o c . water equivalent of calorimeter is 12 g and specific heat is 1 ca..
Calculate the mass of the reaction mixture in the calorimeter. (To do this, assume that the density of the HCl solution originally in the calorimeter can be approximated with the density of water (1.0 g/mL).
Draw the molecule by placing atoms on the grid and connecting them with bonds. Include all lone pairs of electrons.
As well, spectrum a shows significant peaks at m/z 85, 58, 57, as well as 43 while spectrum B shows peaks at m/z 71, 58, and 29. Allocate each compound its correct spectrum and identify the structures of the ions accountable for producing each of ..
From the examples you state, select one acid, one base, and one salt and describe specifically how and where they are used in therapeutic processes. Define a buffer and explain how a buffer works.
