(a) The molecular shapes of cis and Trans forms of N2F2 are-
b) There is EN difference between N atom and F atom. Hence the molecule will have a bond dipole.
In Cis form two fluorine atoms are on the same side of N N bond. Hence, bond moment in N2F2 cis form) do not cancel each other. Thus the cis form is polar.
In the trans form two fluorine atoms are on the opposite side of N-N bond. Bond moment of NF cancels each other.
Thus: trans N2F2 is non polar molecule.
Answer:
Reaction quotient, Q, is 0.44
Explanation:
For the reaction:
C(s)+H₂O(g) ⇌ CO(g)+H₂(g)
Reaction quotient Q, at any course of the reaction, is defined as:
Q = [CO][H₂] / [H₂O]
Concentration of reactants is:
[CO] = 3.20mol / 3.75L = 0.853M
[H₂] = 8.20mol / 3.75L = 2.187M
[H₂O] = 15.9mol / 3.75L = 4.24M
Replacing, Q is:
Q = [0.853][2.187] / [4.24]
<em>Q = 0.44</em>
