Explanation:
Le Chatelier's principle states that for a long period of time if a system is at equilibrium and it is subjected to change in concentration, temperature, volume or pressure then the system shifts to a new equilibrium.
This change will partly counter acts the applied change.
Therefore, when heat is added to the system then equilibrium will shift to the side where temperature or heat is reduced again.
For example, 
Since heat is added to the system, hence, system will shift to the left side or we can say equilibrium will shift to the backward direction.
Answer: Fractional distillation is used to separate liquids with differing boiling points
Explanation:
Sublimation is used to separate volatile substance from a non volatile substance where volatile substance gets converted from solid to gas.
Fractional distillation is separation of a liquid mixture into fractions which differ in boiling points by means of distillation by use of a fractionating column.
Chromatography is a separation method where different rates of adsortion of different components is used to separate substances.
Answer:
<em>Well, Your best answer will be is 2H+ + 2OH- -> 2H2O but you have to reduce it to H+ + OH- -> H2O. </em><em>Good Luck!</em>
Answer:
5) donating H to a solution when they have been depleted and accepting H when they are in excess.
Explanation:
A buffer solution is a solution that undergoes a negligible change in pH in addition of moderate quantities of acid or alkali. In other words, a buffer solution is one that resists a change in pH on addition or dilution of small amounts of acids or alkalis.
So, from the given question:
Buffers are substances that help resist shifts in pH by donating H to a solution when they have been depleted and accepting H when they are in excess.
Answer:
Particles in a liquid move randomly and can slide past each other but they don't move far away from each other. Particles in liquids are close together, rolling over each other and arranged randomly. Particles in a solid vibrate in all directions but cannot move out of their fixed positions.
