Answer:
Water and acetone is best by separated through distillation
The correct answer would be option C Acetone and water.
Explanation:
When in a mixture of fluid solution, two liquids are mixed in a form of mixture then these liquid can be separated only one method which is based on the fact. That two different liquids will have two different boiling temperatures which method of separating the Fluids is distillation.
The different liquids that are present in mixture are boiled and the vapours are condensed and the condensed portion is accumulated in another beaker.
Answer:
C. Combustion
Explanation:
Combustion- an organic compound containing carbon, hydrogen and sometimes oxygen reacts with oxygen gas to form carbon dioxide and water.
Answer:
6.97 atm was the equilibrium pressure of HBr .
Explanation:
The value of the equilibrium constant =
Initially:
0 0 7.10 atm
At equilibrium
x x (7.10-2x)
The expression of equilibrium constant can be written as:
Solving for x:
x = 0.065
Partial pressure of HBr at equilibrium :(7.10 - 2 × 0.065) atm = 6.97 atm
6.97 atm was the equilibrium pressure of HBr .
Answer:
The equilibrium shifts towards reagents
Explanation:
Is known ![Kc=\frac{[products]}{[reagents]}](https://tex.z-dn.net/?f=Kc%3D%5Cfrac%7B%5Bproducts%5D%7D%7B%5Breagents%5D%7D)
rised to the power of their number of moles in the balanced reaction. When you have a system at equilibrium with Kc < 1, it means [products] < [reagents] and the system needs energy to react, so if you decrease tempeture the equilibrium shifts towards reagents and less products will be created.
This efect can be discribed with Van´t Hoff equation: 
where we can see that if we decrease temperature (this is T2<T1) in consecuense K2<K1 and reaction doesn´t happen.
