Answer:

increase

Explanation:

Let's suppose we have a sample of air in a closed container. We heat the container and we want to predict what would happen to the pressure.

According to Gay-Lussac's law, the pressure of a gas is directly proportional to its absolute temperature.

Thus, if we increased the temperature of the air by heating it, its pressure would increase.

If a sample of air in a closed container was heated, the total pressure of the air would increase.

Explain wether or not a reaction takes place when when bromine water is added to sodium chloride solution
CaHeK987 [17]

Answer:

When chlorine (as a gas or dissolved in water) is added to sodium bromide solution, the chlorine takes the place of the bromine. Because chlorine is more reactive than bromine, it displaces bromine from sodium bromide. The solution turns brown. ... The chlorine has gone to form sodium chloride.

<h2>Answer:</h2>

The<u> diffusion </u>occurs in room.

  • <u>Oder molecules move from their highest concentration to lowest concentration.</u>
<h3>Explanation:</h3>

Diffusion is a process by which molecules move down their concentration gradient. The process does not require any membrane.

So corner with perfume has high concentration of odor molecules. Hence they move to other corner with low concentration of molecules.

Electrolysis of molten lead bromide is carried out.
bearhunter [10]

Answer:

Read Below

Explanation:

Electrolysis is not possible with solid lead (II) bromide. This is because the ions are held in a three-dimensional lattice, unable to move freely to the electrodes. Melting enables the ions to become mobile and to travel to the respective electrodes.

The bulb won't glow when the electrodes are embedded in solid lead bromide.  The bulb will glow when the material surrounding the electrodes is molten lead bromide. When an ionic compound is in the molten (liquid) form the positive and negative ions are free to move around.

Hopes this Helps :D
