Three gases (8.00 g of methane, CH4, 18.0 g of ethane, C2H6, and an unknown amount of propane,C3H8) were added to the same 10.0- L container. At 23.0 degrees C, the total pressure in the container is 4.00 atm. Calculate the partial pressure of each gas in the container.Express the pressure values numerically in atmospheres, separated by commas. Enter the partial pressure of methane first, then ethane, then propane.
A fluoridated water supply contains F- at a concentration of 8.9 ppm. What is the maximum concentration of Mg2+ that can exist in this water supply without causing precipitation? The Ksp for MgF2 is 6.4×10-9. Answer in units of grams/L.
(a) reversibly, (b) against a constant external pressure equal to the final pressure of the gas, and (c) freely (against zero external pressure)
Identify the carbon atom(s) in the structure shown that has (have) each of the following hybridizations.
Determine the molar mass of carbon dioxide by measuring the mass of an Erlenmeyer flask full of the gas. The following calculations are intended to familiarize you with the general procedure:
Given that the atomic mass of carbon is given as 12.0107 g/mol, what are the approximate relative abundances of the two isotopes 12C and 13C?
