Answer:
34.653mL or 0.03465L
Explanation:
Density (g/mL) = mass (g) / volume (mL)
The mass of one mole of liquid nitrogen is 14g for one atom × 2 moles = 28mol.
Since density of the liquid nitrogen is 0.808 g/mL, the volume can be calculated thus:
Volume = mass/density
Volume = 28/0.808
Volume = 34.653mL
In litres, the volume will be 0.03465L
Answer: Option (B) is the correct answer.
Explanation:
According to the given reaction equation, formula to calculate is as follows.
= coefficients of gaseous products - gaseous reactants
= 1 - 0
= 1
Also we know that,
For the equation,
Activity of solid and liquid = 1
As,
Hence, = 0.0056 atm
Thus, we can conclude that partial pressure of oxygen gas at equilibrium is 0.0056 atm.
Answer:
for 1 solid its freezing.
for 2 solid and liquid its melting
for 6 liquid to gas its evaporation and for 5 gas to liquid its condensation.

The polar covalent bonding occurs when two atoms with different electronegativity form a covalent bond. This type of connection, the electrons are not equally shared. Typically, the atom having higher electronegativity attracts the electrons in the next link to it, thus forming a negative pole in its vicinity, and a positive pole of the next region less electronegative atom.
example: In the molecule HCl, hydrochloric acid, chlorine atom is more electronegative attracting electrons proximity to the bond with the hydrogen atom that is less electronegative, or more electropositive also rated.
