Gas Law problems ( Chemistry)
the initial temperature of a 1l sample of gas is 20c. The pressure is decreased from 720mmhg to 36mmhg and the volume increases to 2.14l. What was the final temperature of the gas?
How do you expand ln15x? thanks :)
Molar heat of combustion question!
Calculate the molar heat of combustion of paraffin, expressed in units of kJ/mol. First calculate the thermal energy released when one mole of parafin burns) because one mole of parafin (c25h52) has a mass of 325g, the molar heat of combustion will be 352 times greater than th...
