Calculate the heat released when 2.00 L of Cl2(g) with a density of 1.88g/L react with an excess of sodium metal at 25oC and 1 atm to form sodium chloride.
The average January temperature in New Orleans is 56 F. The average July temperature is 83 F. Consider a house in the city that exchanges heat with the outside in accordance with the relation dq/dt = A(To - Ti).
Calculate the vapor pressure of water above a solution prepared by dissolving 35.0 of glycerin () in 135 of water at 343 . (The vapor pressure of water at 343 is 233.7.)
What is the molecular geometry of a molecule with 3 outer atoms and 2 lone pairs on the central atom
Concentrated HCl was added to a Ca(OH)2 suspension (in water) and the precipitate dissolved. Explain this observation on the basis of a Le Chatelier's shift in the equilibrium.
what is the maximum number of grams of [Co(NH3)6]Cl3 that can be produced?
Draw the structure of the carbocation intermediate leading to the formation of 3-methyl-1-butene. Use the (+) and (-) tools to adjust charges as necessary
what would the final common temp be assuming no heat loss? Use Cp for ethanol = 60.0 J K -1 mol -1 and Cp for Copper = 0.380 J K -1 g -1.
The mass of the final solution is 73.0 grams, and its heat capacity is 3.85 J/g°C; the heat capacity of the calorimeter is 5.0 J/°C. Calculate the ?Hreaction in kJ/mol metal.
On the obtained mass-spectra you got in the expected parent-ion mass region two adjacent lines with almost the same abundance (m/z=258 -100%, and m/z=260 -97%). Fragments do not show any adjacent abundant lines. What conclusion can you derive from..
