Answer:
C) As a gas is heated, the pressure decreases.
Explanation:
From the choices given, the statement that "as a gas is heated, the pressure decreases is false".
When gases are heated, their molecules expands and the volume of the gas increases. In a fixed container, the pressure of the gases will also increases.
- Gases lack internal cohesion and very weak to no intermolecular forces binding them together.
- When they are subjected to heat, they gain more energy(kinetic energy) which causes them to begin to spread out.
- Thus, they take up even more space allowing volume to increase appreciably.
There are a couple of ways in which you can express the concentration of a solution, and here they are: gram per liter (g/L), molarity (M), parts per million (ppm.), and percents (%).
As you can see, only M appears in your answers, which means that the correct option should be (2) 3.5 M.

Explanation:
Electrolysis of a subastance is breaking it into its constituents by the action of electrical current.
In the electrolysis of molten sodium chloride, sodium metal is produced at the cathode which is a negative electrode and chlorine gas produces as the anode which is a positive electrode.
At anode :
At cathode :
