If the ball is dropped from a higher height than the feather their rates of displacement (acceleration) could match.
Answer:
Explanation:
<u>1) Equilibrium equation (given)</u>:
- H₂ (g) + I₂ (g) ⇄ 2HI (g)
<u>2) Equilibrium constant expression</u>:
![Kc=\frac{[{HI]}^2}{[H][I]}](https://tex.z-dn.net/?f=Kc%3D%5Cfrac%7B%5B%7BHI%5D%7D%5E2%7D%7B%5BH%5D%5BI%5D%7D)
<u>3) Determine the conentrations from the stoichiometry</u>:
a) <u>Number of moles</u>:
H₂ (g) + I₂ (g) ⇄ 2HI (g)
Start 0.4 1.55 0
Change - 0.4×0.6 = - 0.24 - 0.24 + 0.24×2 = + 0.48
--------------------------- ------------- --------------------------
End 0.16 1.31 0.48
b) <u>Concentrations</u>:
- [ H₂ (g) ] = 0.16 mole / 2 liter = 0.08 M
- [ I₂ (g) ] = 1.31 mole / 2 liter = 0.655 M
- [HI (g) ] = 0.48 mole / 2 liter = 0.24 M
<u>4) Compute Kc</u>:
- Kc = (0.24 M)² / (0.08 M × 0.655 M) = 1.099 ≈ 1.1 ← answer
Answer:
MgCo3+Hcl—Mgcl+Co2+H2o
Explanation:
magnesium carbonated reacting with hydrochloric acid will yield magnesium chloride in addition with carbonIVoxide with water
<span>The answer to this would be radioactive decay. This is also known as "nuclear decay" or "radioactivity".</span>
I think a solid is the answer
