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.
Hydrogen gas is formed when magnesium reacts with hydrochloric acid.
A mixture that results when substances dissolve to form a homogeneous mixture is a solution.
Answer:
molecules of nitrogen gas
Explanation:
In order to convert the mass of a given compound into the number of molecules, we need to:
- identify the number of moles of a given compound dividing its mass by the molar mass,
, - multiply the number of moles by the Avogadro's constant which tells us that 1 mole contains
molecules.
In this problem:
The number of particles is then found by:
