5. Decomposition.
Answer:
Explanation:
Charles law states that "the volume of a fixed mass of gas varies directly as its absolute temperature if the pressure is constant".
This law is a derivative of the kinetic molecular theory of gases.
- The law explained shows that as the temperature of gases increases the volume of gases increases.
- When gases are heated the average kinetic energy of the molecules increases.
- The molecules are independent of one another and they begin to expand out as their velocity surges.
- They take up more spaces in this way.
Answer:
The pH of the solution is 8, 40-
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 greater than 7 to 14 basic. It is calculated as
pH = -log (H30+)
pH= -log (4x10-9M)
<em>pH=8,40</em>
Answer: 12 electrons
<u>If the 3d and 4s bands are superimposed on a metal atom, the maximum number of electrons for this band will be 12 electrons.</u> Remember that in layer 10 you can enter up to 10 electrons in the orbitals that you have, while the s can enter 2, therefore the amount of electrons that will enter the set formed by both bands when superimposed will be 12 electrons
