A mixture is a combination of two or more substances that are physically mixed together without undergoing a chemical reaction. Mixtures can combine substances in any proportion and the components do not change chemically. Mixtures can be either heterogeneous, where each component is visibly separate, or homogeneous, where the components are evenly mixed and cannot be visually separated.

A mixture is a combination of two or more substances that are physically mixed together without undergoing a chemical reaction. Mixtures can be heterogeneous, with each component clearly visible, or homogeneous, where the components are evenly distributed and not visible individually. Mixtures differ from compounds in that their components can be separated by physical means and do not have a fixed composition.Homogeneous mixture
Homogeneous mixtureMartinGeraldine
油
A homogeneous mixture has a uniform composition and cannot be viewed as separate components. It exhibits uniform appearance and properties throughout. Homogeneous mixtures consist of a single phase, whether solid, liquid, or gas. They have identical composition in all parts and appear uniform to the naked eye. Homogeneous mixtures cannot be filtered because the mixture is uniform with no way to separate components. Common examples of homogeneous mixtures include solutions, alloys, air, and other mixtures used in daily life like drinks, cleaners, and blood plasma.Solutions

A mixture forms when油two or more substances are combined such that each substance retains its own chemical identity. Everywhere around us are made up of mixtures. We can see them in nature, along the surface of the earth, in the oceans and in the foods we eat. There are infinite numbers of mixtures that can be combined into homogeneous or heterogeneous.

This document discusses various methods for separating mixtures, including:
- Crystallization to separate sugar from a soft drink by heating and evaporating water.
- Filtration to separate insoluble solids from liquids by passing the liquid through a filter.
- Distillation to separate liquids with different boiling points by evaporating and condensing them.
- Gravity separation to separate mixtures where components have different densities, like gold panning.
- Chromatography to separate colored substances in a mixture.homogenous and heterogenous mixture
homogenous and heterogenous mixtureJessicaRosales31

When salt is added to water, the salt crystals disappear and the water tastes salty, forming a homogenous saltwater mixture where the salt and water particles are evenly mixed on a microscopic level. In a heterogeneous mixture, the individual substances that make it up are not evenly distributed and their particles remain visible, such as a suspension where one substance is suspended in another. The document provides examples of homogenous and heterogeneous mixtures and directs the reader to activities in the textbook to further explore the differences between the two types of mixtures.PURE SUBSTANCES

This document defines pure substances and mixtures. A pure substance is homogeneous and has definite properties, while a mixture contains two or more substances mixed together without chemical change. Solutions are homogeneous mixtures where particle size is molecular. Suspensions are heterogeneous mixtures where particle size is larger, allowing settling. Colloids have intermediate particle sizes that do not settle. The document discusses types of mixtures and their distinguishing characteristics.Dacota_blue K12: Science 7: Quarter 1: Module 1 matter

The document discusses different types of mixtures including homogeneous and heterogeneous mixtures, solution-based mixtures, and solid mixtures. Homogeneous mixtures have a uniform composition while heterogeneous mixtures have a non-uniform composition. Solution-based mixtures can be classified as true solutions, colloidal solutions, or suspensions depending on the particle size of the solute. Solid mixtures include alloys, which are homogeneous solid solutions of metals that are difficult to separate. An example given is brass, which is a homogeneous mixture of copper and zinc that takes on properties between the two metals.SCIENCE7: Types of Mixtures

This document discusses methods for separating mixtures into their pure components. It describes techniques like filtration, crystallization, distillation, and paper chromatography. Filtration can separate insoluble solids from liquids. Crystallization involves evaporating a solution to leave behind crystals of the solute. Distillation separates liquids based on their boiling points. Paper chromatography uses a solvent to separate mixtures on a paper strip based on how far different substances travel up the paper. The document emphasizes that pure substances have fixed melting and boiling points, while mixtures can be separated into pure components using these techniques.Separating mixtures

A mixture is when two or more substances are mixed together without chemically combining. Mixtures can be separated into their original substances using physical means. Some common ways to separate mixtures include magnetism, filtration, sieving, extraction, and chromatography. Magnetism uses magnets to separate mixtures where one substance is magnetic. Filtration separates solids from liquids by passing the mixture through a porous filter. Sieving separates substances of different sizes by passing the mixture through a sieve with tiny holes. Extraction separates soluble and insoluble substances by dissolving one in a solvent and filtering out the other.Separating mixtures (Grade 7)

An element is a pure substance that cannot be separated into simpler substances. Elements have unique characteristic properties like melting point and reactivity that can be used to identify them. Elements are grouped into metals, nonmetals, and metalloids based on shared properties. Compounds are formed when two or more elements chemically combine to form a new substance with different properties. Mixtures are combinations of substances that do not chemically combine and can be separated physically.Types of mixture

The document discusses how the state of matter can be changed by changing temperature or pressure. It explains that matter can exist as solids, liquids, or gases, and provides examples like water existing as ice, liquid water, or steam. Changing temperature can cause melting, boiling, condensation, or freezing as matter transitions between states. Similarly, changing pressure can liquefy gases by compressing and cooling them, or change solid carbon dioxide into a gas by decreasing pressure. In summary, temperature and pressure are the two factors that determine the physical state of a substance.Properties of Mixtures and Pure Substances

Here are brief explanations of the key concepts:
- The composition of an element is fixed because elements are pure substances made of only one type of atom.
- The composition of a compound is also fixed, but compounds contain two or more elements combined in a fixed ratio.
- Properties of mixtures can vary because mixtures are combinations of two or more substances that are not chemically combined. Their compositions are not fixed.
- Mixtures can be classified as solutions, suspensions, or colloids based on whether the mixed substances are uniformly dispersed (solutions), settle over time (suspensions), or are dispersed with particles too small to settle but large enough to scatter light (colloids).

The solubility curves provide the maximum amount of solute that can dissolve in a specified amount of solvent (usually 100g) at a given temperature.
1) According to the NH4Cl curve, the maximum amount that can dissolve in 100g of water at 40属C is ~45g. Since 50g is dissolving, it is supersaturated.
2) The KNO3 curve shows that ~65g can dissolve in 100g of water at 70属C. Since we have 50g of water, we can scale down proportionally to find the maximum amount of KNO3 is ~32.5g.

This document discusses physical and chemical properties of matter. It defines matter as anything that has mass and volume, and identifies the three common states of matter as solids, liquids, and gases. Physical properties can be observed without changing the identity of the substance, such as color, odor, and density. Chemical properties describe a substance's ability to undergo chemical reactions, like flammability or reactivity. A physical change alters the state of matter without changing its chemical makeup, while a chemical change produces new substances with different properties.Solutions, suspensions, and colloids
