Answer:
Kc = 9.52.
Explanation:
<em>A + 2B ⇌ C,</em>
Kc = [C]/[A][B]²,
Concentration: [A] [B] [C]
At start: 0.3 M 1.05 M 0.55 M
At equilibrium: 0.3 - x 1.05 - 2x 0.55 + x
0.14 M 1.05 - 2x 0.71 M
- For the concentration of [A]:
∵ 0.3 M - x = 0.14 M.
∴ x = 0.3 M - 0.14 M = 0.16 M.
∴ [B] at equilibrium = 1.05 - 2x = 1.05 M -2(0.16) = 0.73 M.
<em>∵ Kc = [C]/[A][B]²</em>
∴ Kc = (0.71)/(0.14)(0.73)² = 9.5166 ≅ 9.52.
Answer:
Chlorophyll absorbs light energy, ATP molecules form, sugar molecules form. I'm pretty sure this is correct, but if it is not I'm sorry...
Explanation:
Answer:
The answer is
<h2>29.48 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume of lead = 2.6 cm³
density of lead = 11.34 g/cm³
The mass of lead is
mass = 11.34 × 2.6 = 29.484
We have the final answer as
<h3> 29.48 g</h3>
Hope this helps you
<span>there is no answer so i think it should be -ate. not sure tho without the options
