The property of liquid oxygen that makes it especially difficult and potentially harmful to work with at home would be its cryogenic temperature. Liquid oxygen is being produced from the compression of oxygen gas to -196 degrees Celsius. As you can see, it has a very cold temperature that is why it used in cryogenics. Although liquid oxygen is non-toxic to humans, it would cause burns that are severe when being touched. Also, it would make certain materials brittle and unstable. Another property that makes it dangerous for use at home would be that it is very flammable. Proper handling is a must for this substance.
Answer: 94.13 L
Explanation: In STP in an ideal gas there is a standard value for both temperature and pressure. At STP,pressure is equal to 1atm and the temperature at 0°C is equal to 273.15K. This problem is an ideal gas so we use PV=nRT where R is a constant R= 0.08205 L.atm/mol.K.
To find volume, derive the equation, it becomes V=nRT/P. Substitute the values. V= 4.20 mol( 0.08205L.atm/mol.K)(273.15K) / 1 atm = 94.13 L. The mole units, atm and K will be cancelled out and L will be the remaining unit which is for volume.
Answer:
duplet-A set of two things or people
Octet-A group of 8 things or people
Atoms
Explanation:
Chemical bonds results from the rearrangement of atoms in a chemical species.
It deals with the various attractive forces joining chemical species togethe.
- When atoms are re-arranged, they form chemical bonds that leads to production of new compounds.
- This is made possible by the exchange or sharing of electrons.
- The driving force for most interatomic bonding is the tendency to have completely filled outer energy levels like the noble gases.
- When atoms are re-arranged in compounds they lead to the production of chemical bonds.
