Has two or more substances that are evenly spread out?
A mixture is made when two or more substances are combined, but they are not combined chemically. There are two main categories of mixtures: homogeneous mixtures and heterogeneous mixtures. In a homogenous mixture all the substances are evenly distributed throughout the mixture (salt water, air, blood).
Does a solution spread out evenly?
Solutions are groups of molecules that are mixed and evenly distributed in a system. Scientists say that solutions are homogenous systems. Everything in a solution is evenly spread out and thoroughly mixed.
Is a solution consists of two or more evenly distributed substances?
A solution is a uniform mixture where two components are evenly distributed. The particles of each are very small and become completely mixed together. (This is unlike a suspension, in which the particles are bigger and not completely dissolved in the liquid.) A solution is a homogeneous mixture.
When two materials mixed evenly and do not settle that mixture is called?
Types of Mixtures (Definitions)
| A | B |
|---|---|
| mixture | 2 or more substances that are physically mixed together but not chemically combined |
| colloid | a mixture containing small, undissolved particles that do not settle out |
| suspension | a mixture in which particles can be seen and easily separated by settling or filtration |

What are the two types of pure substances?
By their chemical composition, pure substances get divided into two types – elements and compounds.
What is dissolve evenly?
Making Solutions A simple solution is basically two substances that are evenly mixed together. One of them is called the solute and the other is the solvent. A solute is the substance to be dissolved (sugar). The solvent is the one doing the dissolving (water).
What mixture is not well mixed?
Homogeneous mixture is a well mixed mixture but heterogeneous is not. that are large enough to be seen. -A mixture is a combination of two or more pure substances. Colloid is the homogeneous mixture that are mixed together but not dissolve, while a solution is when the substance dissolves in another.
What is least mixed mixture?
Heterogeneous – A mixture that does not appear to be the same throughout. The “least-mixed of mixtures”.
Which particles interact during the dissolving process?
In the case of a solid or liquid solute, the interactions between the solute particles and the solvent particles are so strong that the individual solute particles separate from each other and, surrounded by solvent molecules, enter the solution.
What is the rule like dissolves like used to predict?
A popular saying used for predicting solubility is “Like dissolves like.” This statement indicates that a solute will dissolve best in a solvent that has a similar chemical structure; the ability for a solvent to dissolve various compounds depends primarily on its polarity.
What makes a solution different from other mixtures?
A solution is a mixture of two or more substances, but it’s not just any mixture. A solution is a homogeneous mixture. In a homogeneous mixture, the dissolved particles are spread evenly through the mixture. The particles of the solution are also too small to be seen or to settle out of the mixture.
Which is an example of a solution that dissolves?
The solute is the substance that dissolves, and the solvent is the substance that dissolves the solute. Particles of solvent pull apart particles of solute, and the solute particles spread throughout the solvent. Salt water, such as the ocean water in the Figure below, is an example of a solution.
What are the two parts of a solution?
Solutions may be liquids such as salt water, solids such as alloys, or gases such as air. What is a solution? Identify and describe the two parts of a solution. Give an example of a substance that is soluble in water and a substance that is insoluble in water.
Which is the correct definition of a solution?
A solution is a mixture of two or more substances, but it’s not just any mixture. A solution is a homogeneous mixture. In a homogeneous mixture, the dissolved particles are spread evenly through the mixture.
