Question:
Infrared (IR) spectroscopy is a highly useful tool for probing gas samples. A certain IR analyzer is used to probe a carbon monoxide gas sample, which contains no chemical impurities. Predictably, a stretch band at 2045 cm-1 was registered.
Your colleague suggested that more stretch bands at various frequency (wavenumber) values and of possibly lower intensity could be detected for this sample.
State how many stretch bands could you expect to register for this sample, explain what the reason for the multiple bands can be and predict their wavenumber values in units of cm-1.
How many stretch bands in total do you predict :____
Wavenumber values (in cm 1): 2045 _______
Reason for multiple bands to be expected ______
Calculations and justification ______
If a sample of hydrogen has a volume of 582 mL when the temperature is 48.6 degC and the pressure is 1.116 atm. Explain what will be the volume of the gas at STP
