Answer:
energy goes into the chemical and cool downs the surrounding area.
It's usually water and a type of salt take the reaction between hydrochloric acid and sodium hydroxide HCl(aq)+NaOH(aq) yeilds NaCl(aq) and H2O(l)
Answer:
The formula for pressure is P = F/A, in which P is pressure, F is force, and A is area.
Explanation:
Moles = mass/molar mass
moles = 2.3
molar mass = 278
=> mass = moles*molar mass = 639.4g
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.
