Temperature also affects the motion of atoms in a gas. Given what you know about temperature, pressure, and volume, which statem
vampirchik [111]

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.

Elis [28]
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.

If molten sodium chloride is split by electrolysis, which reaction occurs at the anode?
mariarad [96]

Answer: 2Cl^-(l)\rightarrow 2e^-+Cl_2(g)

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.

2NaCl(l)\rightarrow 2Na^++2Cl^-

At anode : 2Cl^-(l)\rightarrow 2e^-+Cl_2(g)

At cathode : 2Na^+(l)+2e^-\rightarrow 2Na(l)
