Answer:
A) Concentration of A left at equilibrium of we started the reaction with [A] = 2.00 M and [B] = 2.00 M is 0.55 M.
B) Final concentration of D at equilibrium if the initial concentrations are [A] = 1.00 M and [B] = 2.00 M is 0.90 M.
[D] = 0.90 M
Explanation:
With the first assumption that the volume of reacting mixture doesn't change throughout the reaction.
This allows us to use concentration in mol/L interchangeably with number of moles in stoichiometric calculations.

Answer:
4.79 J
Explanation:
The energy of a single photon is given by
where
is the Planck constant
f is the frequency of the photon
Here we have
so the energy of one photon is
Here we have 1 mol of photons, which contains
photons (Avogadro number). So, the total energy of this mole of photons is:
Answer:
g = 0.905 gE
W = 67.9 N
Explanation:
given data
mass of Venus mv = 81.5% = 0.815
radius Rv = 94.9% = 0.949
weighs W = 75.0 N
solution
we apply here acceleration due to gravity at earth surface that is
g = = 9.80 m/s² ............1
so
g =
g = 0.905 gE
and
W = m gv
W = 0.905 m gE
W = 0.905 × 75
W = 67.9 N
