What pressure must be applied to keep a gas at 750 torr and 300 K at a constant volume of 200 mL if the temperature is raised to
2 answers:
Answer:
The pressure must be applied at 450 K should be 1,125 torr.
Explanation:
At constant volume of 200 mL
Initial pressure exerted by the gas =
Initial temperature of the gas =
Final pressure exerted by the gas =
Final temperature of the gas =
Applying Gay Lussac Law:
The pressure must be applied at 450 K should be 1,125 torr.

Answer:
In the 1H NMR spectrum of ethanol three different signals are observed, this is due to the existence of 3 types of hydrogens with different chemical environment. Hydrogens A (3.57 ppm) are more screened than C (1.10 ppm) due to the presence of oxygen (electonegative atom that removes electron density). The chemical environment of hydrogen B (4.78 ppm), attached directly to oxygen, is also different by resonating at a frequency different from the previous ones.
The hydroxylic hydrogen produces a singlet, the pair of carbon hydrogens one give rise to a quadruplet and the three hydrogens of carbon two produce a triplet.
