Answer:
pH= 3, 00 (acidic solution), pOH= 7,00
Explanation:
The pH indicates the acidity or basicity of a substance. PH values between 0 and less than 7 indicate acidic solutions, 7 neutral and higher than 7 to 14 basic. It is calculated as
pH = -log (H 30+)
pH= -log (0.001)
pH=3, 00 (the solution is acidic because the pH is less than 7,00)
We know that the sum of the pH and pOH is 14, so we solve pOH:
pH + pOH= 14
3, 00 + pOH=14
pOH= 14 - 3,00= 7, 00
Answer:
Solid state : In this state, the molecules are arranged in regular and repeating pattern. The molecules are closely packed that means they are fixed and vibrate in place but they can not move from one place to another. They have least kinetic energy. For example : chair
Liquid state : In this state, the molecules are present in random and irregular pattern. The molecules are closely packed but they can move from one place to another. They have more kinetic energy than solids but less than that of gases. For example : oil
Gaseous state : In this state, the molecules are present in irregular pattern. The molecules are not closely packed and they can move freely from one place to another and spread out. They have most kinetic energy. For example : Hydrogen
