Dry ice is solid carbon dioxide. A 1.87g sample of dry ice is placed in an evacuated 4.03 L vessel at 22 degrees C. Calculate the pressure inside the vessel after all the dry ice has been converted to CO2 gas
calculate the initial reaction rate when [O3] & [NO] remain essentially constant at the values [O3]0= 7.48 x 10-6 M & [NO]0= 3.26 x 10-5M
Calculate the molar heat (enthalpy) of combustion for butyric acid.
"disappeared" from a rock face that is adjacent to a lake (original pH=6.7) with dimensions 100 m x 40 m x 10 m. You think that the "disappearance" is due to leaching of the pyrite into the lake. To prove your point, what would the new pH of the l..
