Answer:

2.Closed System: A closed system is a thermodynamic system where energy can be exchanged with its surrounding but not matter. Open System: Open systems can exchange matter with the surrounding. Closed System: Closed systems cannot exchange matter with the surrounding. Open System: The mass of the system will vary with time in open systems.

Explanation:

1.The particle model is the name for the diagrams used to draw solids, liquids and gases. In the model, the particles are shown as circles or spheres. However, the particles in ice, liquid water and steam look the same because they are all water, but in different states of matter. Why do we use the particle model in science?

3.An open system can be defined as a system which can exchange both matter and energy with the surrounding. For example, the earth can be recognized as an open system. In this case, the earth is the system, and space is the surrounding. Sunlight can reach the earth surface and we can send rockets to space.

Thermal energy is a form of
Mrrafil [7]

Thermal energy is an example of kinetic energy, as it is due to the motion of particles, with motion being the key. Thermal energy results in an object or a system having a temperature that can be measured. Thermal energy can be transferred from one object or system to another in the form of  heat.                hope this helps

If 1.0 M HIM HI is placed into a closed container and the reaction is allowed to reach equilibrium at 25∘C∘C, what is the equili
sattari [20]

The given question is incomplete. The complete question is

If 1.0 M HI is placed into a closed container and the reaction is allowed to reach equilibrium at 25∘C∘C, what is the equilibrium concentration of H2 (g). Given the equilibrium constant is 62.

Answer: The equilibrium concentration of H_2 is 0.498 M

Explanation:

Initial concentration of HI = 1.0 M

The given balanced equilibrium reaction is,

                         2HI(g)\rightarrow H_2(g)+I_2(g)

initial                  (1.0) M                  0              0

At eqm               (1.0-2x) M               (x) M      (x) M

The expression for equilibrium constant for this reaction will be,

K_c=\frac{[H_2]\times [I_2]}{[HI]^2}

Now put all the given values in this expression, we get :

62=\frac{(x)^2}{1.0-2x}

By solving we get :

x=0.498M

Thus the equilibrium concentration of H_2 is 0.498 M

Which statement is true of magnets
Harrizon [31]

The statement that is true about magnets is ''Similar poles of a magnet repel each other.''

<h3>What are the characteristics of magnet?</h3>

All magnets have both north and south poles. Opposite poles attract each other, whereas the similar poles repel each other. When you rub a piece of iron along a magnet, this force creates a magnetic field.

So we can conclude that The statement that is true about magnets is ''Similar poles of a magnet repel each other.''
