What are the ionic bonds
zhuklara [117]

Explanation:

Ionic bonds are bonds formed as a result of the electrostatic attraction between two species.

  • This bond type is an interatomic bond.
  • It forms when two specie with a large electronegative difference between them combines.
  • This is usually a metal and a non-metal.
  • The metal loses its valence electrons and becomes positively charged.
  • The non-metal gains the electron and becomes negatively charged.
  • An electrostatic attraction between the two specie leads to the formation of an ionic bond.
  • They are solids with a high melting point.
  • They are soluble in polar solvents.

The volume (in L) that would be occupied by 5.00 mols of 02 at STP is
crimeas [40]

Answer : The volume of oxygen at STP is 112.0665 L

Solution : Given,

The number of moles of O_2 = 5 moles

At STP, the temperature is 273 K and pressure is 1 atm.

Using ideal gas law equation :

PV=nRT

where,

P = pressure of gas

V = volume of gas

n = the number of moles

T = temperature of gas

R = gas constant = 0.0821 L atm/mole K   (Given)

By rearranging the above ideal gas law equation, we get

V=\frac{nRT}{P}

Now put all the given values in this expression, we get the value of volume.

V=\frac{(5moles)\times (0.0821Latm/moleK)\times (273K)}{1atm}=112.0665L

Therefore, the volume of oxygen at STP is 112.0665 L
