Answer:
a richter scale measures the magnitude of an earthquake so in my own words i would say the richter scale measures the size of an earthquake and letting us kniw how big it will be to prepare for it.
Answer:
a. 0.27 = Kc
b. 8.19×10⁻⁵ = Kp
Explanation:
The reaction is this: 3H₂(g) + N₂ (g) ⇄ 2NH₃ (g)
As we have the moles of each in the equilibrium and the volume is 1L, we assume the concentrations as molarity.
1.6981 mol/L → H₂
0.5660 mol/L → N₂
0.8679 mol/L → NH₃
Let's make the expression for Kc
Kc = [NH₃]² / [N₂] . [H₂]³
Kc = 0.8679² / 0.5660 . 1.6981³
Kc = 0.27
Let's calculate Kp, derivated from Kc
Kp = Kc . (RT)^Δn where:
Δn is the difference between final moles - initial moles. It is governed by stoichiometry. For this case 2 - (1+3) = -2
Δn it is always for gases
R is the Ideal gases constant
T is Absolute T°
Let's replace data → 0.27 . (0.082 . 700K)⁻² = Kp
8.19×10⁻⁵ = Kp
she will have to listen to all of carefully while she is writing for example:
she will listen and look at her writing page (where she writes) she looks while she listens and writes what she hears for example again:
(pretend as i am her.)
"Hey mom, dad, brother come i see crabs!" as she writes it she focuses on how she writes and stops the video and back up again to listen so she can see if it was correct.
