Answer:
Explanation:
Compared to the process of extracting lithium from mineral deposits, the process of extracting lithium from evaporation ponds requires __less____ water, __less____ money, and ___less________ time.
Lithium extraction from salar brines are more economical to extract compared to extraction from their natural ore deposits. Salar brines occurs as liquid underground brine reservoirs. Once pumped to the surface in ponds, they are left to evaporate and the lithium is concentrated from them. Extraction from brines in ponds do not require water that much, less cost and if the evaporation rate is fast, a lot of time can be saved.
Extraction from mineral deposits require a lot of energy and time to achieve.
A way of building knowledge about the world around us through observation and experimentation.
Answer:
Shift it toward the products
Explanation:
Imagine this equilibrium:
2A + B ⇄ A₂B
Let's think the expression for Kc:
Kc = [A₂B] / [A]² . [B]
Now, we have this situation:
2A ↑ + B ⇄ A₂B
As we are not in equilibrium, we have to think that Kc would decrease.
↓Kc = [A₂B] / [A]² ↑ . [B]
so we have to use Qc (reaction quotient). For this case
Qc < Kc, so the reaction → Product side
We have to make more product to counteract the reagent increase and thus return the system to equilibriumr
