Answer:
See explanation
Explanation:
Qualitative analysis in chemistry is a method used to determine the ions present in a solution chiefly by means of chemical reactions.
In this case, I suspect the presence of silver ions and/or barium ions. The first step is to add dilute HCl. This will lead to the precipitation of the silver ion as AgCl. If a white precipitate is formed upon addition of HCl then Ag^+ is present in the solution.
Secondly, I add a carbonate such as NH4CO3(aq). This will cause the barium ions to become precipitated as barium carbonate. Hence, the formation of a white precipitate when NH4CO3(aq) is added to the solution indicates the presence of barium ion in the solution.
Density as you should know is equal to mass/volume. Solve for the volume.
Now, you know that you are dealing with a sphere. You know the volume of a sphere is V= 4/3pi r ^3.
You know the volume so just solve for r

Answer:
Average kinetic energy of the particles in an object.
Total energy of particles in an object.
Explanation:
Thermal energy is the _average kinetic energy of the particles in an object____ and internal energy is the ___total energy of particles in an object__.
Thermal energy is a form of kinetic energy. Kinetic energy is due the change in position of a body or the motion of a body. When we apply thermal energy to a system, the particles gain kinetic energy which causes the motion of its particles.
The internal energy of system is the sum of all the total energy of particles contained in the object. It is given as the change between the kinetic and potential energy of a system.
