The gas pressure in an oxygen tank is 3.90 atm at a temperature of 298 K. If the pressure decreases to 3.20 atm, what is the temperature of the gas in kelvin?

The cyanide ion (CN) is highly toxic, but can be remediated in solution by redox reaction with the hypochlorite ion (the principal component of bleach).

Facts about the outer core

What kind of bond joins hydrogen to oxygen in a water molecule?

What is the heat of combustion per mole of quinone?

HCN forms when synthetic fibers containing Orlon® or Acrilan® burn. Acrilan® has an empirical formula of CH2CHCN, so HCN is 50.9% of the formula by mass. A rug in the laboratory measures 12.0 * 11.0 ft and contains 30.
