The following reaction was carried out in a 3.00 L reaction vessel at 1100 K:
Nady [450]

Answer:

Q=0.840

Explanation:

Hello,

In this case, since the given undergoing chemical reaction is correctly balanced, the reaction quotient is computed as well as the equilibrium constant but in terms of the given concentrations that are:

C_{C}=\frac{5.25mol}{3.00L} =1.75M\\C_{H_2O}=\frac{12.2mol}{3.00L} =4.07M\\C_{CO}=\frac{3.90mol}{3.00L}=1.30M\\C_{H_2}=\frac{7.90mol}{3.00L} =2.63M

In such a way, the reaction quotient turns out:

Q=\frac{C_{CO}C_{H_2}}{C_{H_2O}}=\frac{1.30M*2.63M}{4.07M}\\ Q=0.840

Taking into account that carbon is not included since it is solid.

Best regards.

What is the energy of a photon of red light that has a frequency of 4.48 X 10^14Hz?
lana [24]

Answer:

E = 29.7× 10⁻²⁰  j

Explanation:

Given data;

Frequency of light = 4.48 × 10¹⁴ Hz

Energy of photon = ?

Solution:

Formula:

E = h.f

E = energy of photon

h = planck's constant

f = frequency

E = h.f

E = 6.63 × 10⁻³⁴ Kg.m² /s × 4.48 × 10¹⁴ s⁻¹

E = 29.7× 10⁻²⁰ Kg.m²/s²

Kg.m²/s² = j

E = 29.7× 10⁻²⁰  j
