Calculate the volume (in mL) of 1.2 mol of a perfect gas at 25.0C and a pressure of 1.02 atm.
That would mean it wouldn't have any electrons to give. Can anyone answer this for me as to why there are 28 electrons being transferred if hydrogen has a oxidation state of +1 meaning it doesn't have any electrons to give?
Suppose that 155g of ethanol at 21 degrees Celcius is mixed with 240g of ethanol at 88 degrees Celcius at constant atmospheric pressure in a thermally insulated vessel. What is the change in S of the system for the process? The specific heat capac..
