Answer:
Concentration of A at equilibrium = 1 - 0.5 = 0.5 M
Explanation:
Equilibrium constant = 0.5
Initial concentration of A = 1 M
Initial 1 0 0
At equi. 1-x x x
Equilibrium constant = ![\frac{[B][C]}{[A]}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BB%5D%5BC%5D%7D%7B%5BA%5D%7D)
on solving,
x = 0.5 M
Concentration of A at equilibrium = 1 - 0.5 = 0.5 M
So 500/110=4.54545455, so 4.54545455 rounded to the nearest hundredth is 4.55 miles!
4. If you evaporate the water first, then the sand and salt will be nearly impossible to separate. That eliminates 1 and 2. You can't filter salt out from an aqueous solution, so that eliminates 3. 4 works because you can filter out the sand (which doesn't dissolve) then evaporate the water away from the salt.
