Answer:

The dye particles and the water molecules move causing them to move into one another. This makes them mix.

Answer:

Random movements of the dye and water molecules cause them to bump into each other and mix. Thus, the dye molecules move from an area of higher concentration to an area of lower concentration. Eventually, they are evenly spread throughout the solution. This means the molecules have reached a dynamic equilibrium.

Why are mass and volume not properties of substances

masha68 [24]

Answer:

Extensive properties, such as mass and volume, depend on the amount of matter being measured. Intensive properties, such as density and color, do not depend on the amount of the substance present. Physical properties can be measured without changing a substance's chemical identity

The potential energy diagram shows the gain and loss of potential energy as water molecules decompose into hydrogen and oxygen.

Dovator [93]

Answer:

The diagram with the five labels of the parts is in the image attached. Please, see the image.

Explanation:

1) General explanation: a potential chemical energy diagram is used to show how the reactants gain energy until they reach the activation energy, form the activated complex, and release part of the energy to form the products.

The difference between the chemical potential energy of the products and the reactants is the enthalpy of the reaction:

ΔH rxn = ΔH products - ΔH reactants.

The labels that correspond to each part of the diagram are explained next.

2) Reactants:

This is the substances at the start, so they appear on the left bottom side of the diagram.

3) Activation energy:

It is the energy that the reactants must reach (the highest point) in order to the reaction occurs.

4) Activated complex:

This is the intermediate state and of highest energy. The reactants have formed a complex at mid way between the reactants and the products.

5) Products:

These are the substances formed when the reaction is completed. They are lower in energy than the activated complex. They can be either higher or lower in energy than the reactants. The products are shown to the right of the diagram.

6) Enthalpy of the reaction:

The enthalpy of the reaction is the difference in energy of the products and the reactants. In this case, since, the products are higher in energy, it means that the reaction absorbed energy and it is an endothermic reaction.

Which of the following formulas represents an ionic compound?

Marta_Voda [28]

Answer:

BaI2

Explanation:

Hello, since the electronegativity of Barium and Iodine are 0.89 and 2.66, respectively, the difference is 1.77, so the bond is ionic.

Best regards.

A+uniform+cube+is+subjected+to+volume+expansion. +if+each+side+is+decreased+by+1%,+then+bulk+strain+is

laiz [17]

A uniform cube is subjected to volume expansion. Each side gets decreased by 1%, then the bulk strain is 0.03.

<h3>What is Volume?</h3>

Volume is the space occupied by a three-dimensional object.

<h3 />

Given that, the side cube is l, then

volume V = l³

$\dfrac{\Delta V}{V} = \dfrac{3D1}{1}$

For change in volume

% Change in volume = 3× % change in length

= 3 × 1%

Hence, bulk strain = 0.03.

Thus, the bulk strain is 0.03.
