The system will adjust itself in order to resist the change.
Explanation:
- Frenchman Le Chatelier in 1888 is credited with the Le Chatelier's principle
- His principle is a summary drawn from his findings on various factors that affects equilibrium.
- The principle states that "if any of the conditions of a system in equilibrium is changed, the system will adjust itself in order to annul the effect of the change".
- It is used to explain the effect of stress by applying change on a system.
- The changing conditions are usually concentration, temperature and pressure.

Explanation:
chemical formula tells you the specific elements included in the compound and the number of atoms of each. The letters in a chemical formula are the symbols for the specific elements. So for example, H means hydrogen.
Answer:
The answer is sodium which is the element is the most reactive.
Answer:
The new pressure in the balloon is 16.3 atm
Explanation:
Gay-Lussac's law establishes the relationship between the temperature and the pressure of a gas when the volume is constant.
This law establishes that pressure and temperature are directly proportional quantities, that is to say that if the temperature increases the pressure increases and if the temperature decreases the pressure decreases.
Mathematically, Gay-Lussac's law states that, when a gas undergoes a constant volume transformation, the quotient of the pressure exerted by the gas temperature remains constant:
When you want to study two different states, an initial one and a final one, of a gas, you can use the expression:
In this case:
- P1= 14.7 atm
- T1= 273 K
- P2= ?
- T2= 303 K
Replacing:
Solving:
P2= 16.3 atm
<u><em>The new pressure in the balloon is 16.3 atm</em></u>
When the crystals of potassium permanganate are preserved in water, the purple-coloured crystals of potassium permanganate break further into smaller particles that populate the distance between the molecules of water imparting a purple colour to the water. This is an example of diffusion.
<h3>What are the two conclusions given out in the method of diffusion?</h3>
Diffusion is the process of movement of solvent from higher concentration to lower concentration through a semipermeable membrane. So, we can form the decision that it cannot occur through a thick membrane from which small molecules cannot pass through.
<h3>What is difference between osmosis and diffusion?</h3>
Osmosis is the direction of solvent particles from a solution that is diluted to a more concentrated one. In contrast, diffusion is the movement of particles from a higher concentration region to a part of lower concentration.
