If there's just some barium put in an aqueous solution, then it should be something like this.
It's a mixture of a solution and an insoluble solid, so the easiest way to go is through filtration. (Also, I'm assuming the barium is cut into very small chips.)
In a line, simply filter the solution using a folded filter paper in a funnel, collect the residue in a beaker or flask, rinse it with distilled water and let it dry. (Or simply filtering it could be enough, depending on how far your teacher wants you to go.)
Stuff needed:
>filter paper (for separating the solid from the solution)
>funnel (to hold the filter paper)
>beaker or flask (to hold the filtrate)
>distilled water (to rinse the solid)
>spatula (to scoop up the solid)
Procedure:
>Fold filter paper and line the funnel with it. Place the funnel in the flask or beaker.
>Pour solution in. Then add water (I think using tap water might be fine in this case, but you can use distilled water if you'd like) to wash out the container with the solution of any solid you may have not gotten in the first try. Alternatively, you could use a spatula to spoon it onto the filter paper.
>Once everything has been filtered, pour some distilled water on the residue on the filter paper to wash away the solution.
>Take out the filter paper, open it up and let it dry.
This can be used in real life in many occasions. For example, when you make tea, you need to filter the leaves out. Or when you cook the pasta, you put it in a sieve to separate the pasta from the water. Or when you fish using fishing nets, you "filter" the fish from the water.

All Are correct responses
Answer:
Explanation:
The chemical elements are arranged in order of increasing atomic number. The horizontal rows are called periods and the vertical columns are called groups. Elements in the same group have similar chemical properties. This is because they have the same number of outer electrons and the same valency.
The correct statement is that the average kinetic energy of the gas particles is greater in container A because its particles move faster.
<h3>What is the relation between temperature & kinetic energy?</h3>
Kinetic energy of any particle is directly proportional to the temperature of the sample of that particle.
From the given diagram, it is clear that:
- In beaker A, heat is supplied to the beaker due to which temperature of the beaker A increases as a result of it particles of gases will move with faster velocity because kinetic energy of the gases particle increases.
- Beaker B is present at room temperature, so particles in this beaker will have less velocity as compared to beaker A.
Hence, the average kinetic energy of the gas particles is greater in container A because its particles move faster.
