Scene B depicts chemical change in matter at atomic change.

Composition distinguishes a chemical reaction from a physical reaction. In a chemical process, the makeup of the components changes; in a physical change, the appearance, smell, or straightforward exhibition of a sample of matter changes without changing its composition. Despite the fact that we refer to them as physical "reactions," nothing is actually changing. A change in the substance in question's elemental composition is necessary for a reaction to occur. Therefore, from now on, we will simply refer to bodily "reactions" as physical changes.

If 3.25 mol of Ar occupies 100. L at a particular temp and pressure, what volume does
gtnhenbr [62]

Answer:

435.38 L

Explanation:

From the question,

Applying ideal gas equation,

PV = nRT................... Equation 1

Where P = Pressure, V = Volume, n = number of moles, R = molar gas constant, T = Temperature.

Since Temperature and Pressure were constant,

V ∝ n

V/n = V'/n'.................... Equation 2

Where V and V'  = the initial and final Volume of Ar respectively, n and n'  = the initial and final moles of Ar respectively

make V' the subject of the equation

V' = Vn'/n............... Equation 3

Given: V = 100 L, n = 3.25 mol, n' = 14.15

Substitute into equation 3

V' = (100×14.14)/3.25

V' = 435.38 L

Match each state of matter with the statement that best describes it.
Stells [14]

Answer:

State of matter is defined as a form in which matter can exist. There are four states of matter known till date. They are as follows:

Solid: Matter is said to be in solid state if it has definite shape and volume. The components of matter are closely packed and have fixed positions within the matter.

Liquid: In liquid state, matter has fixed volume but shape is not fixed, it takes the shape of container in which it is placed. The particles of liquid are close but can move freely or do not have fixed positions.

Gas: Matter in gaseous state has variable volume and shape. The particles of gas are very far from each other thus, they are in constant motion without any fixed position..

Plasma: This state of matter has variable shape and volume. It has neutral atoms, the number of ions and electrons are significant and can move freely in the matter. In order to make plasma, energy is required to strip electron from atom.

According to above definitions, the state of matter is matched with the given statements as follows:

Plasma-Particles are so hot that electrons are stripped from atoms.

Gas-It expands to fill the volume of the container.

Liquid-Particles move past each other freely but do not go fat apart.

Solid-It retains its shape regardless of the shape of the container.

Explanation:

I choose this because It understands how each plasma work.
