Ethylene glycol,C2H4(OH)2, is a colorless liquid used as automobile antifreeze. If the density at 20 degree Celcius of a 4.028m solution of ethylene glycol in water is 1.0241g/mL, What is the molarity of the solution? (use density to convert from molality to morality)
what we observed that 1.00 mole Hydrogen, 1.00 mol Iodine and 1.00 mole hydrogen iodide are introduced into a container of capacity 1.00-L. compute the concentrations of each species if equilibrium is reached?
The normal melting points and boiling points of xenon are -112 deg. Celsius and -107 deg. Celsius, respectively. The Xe triple point is at -121 deg. Celsius and 282 torr, and its critical point is at 16.6 deg. C and 57.6 atm.
3 moles of carbon dioxide gas expands reversibly in a piston-container from 20 L to 40 L in an isothermal process at 400 K. Calculate work, heat, change in internal energy and change in enthalpy, considering van der Waals behaviour. [a = 3.59 atm ..
