Mixtures consist of two or more substances that are physically combined, allowing each component to retain its individual properties, while compounds are formed when substances chemically bond, resulting in new properties. Additionally, mixtures can be separated through physical means, such as filtration or distillation, whereas compounds require chemical reactions to separate into their constituent elements.
What else can I help you with?
What are the similarities pure substance and mixtures?
They are both compounds; They both have more than 2 atoms or substances
What are 2 names of mixtures?
two mixtures are hot chocolate and juice or vinegar and lemonade.
How are mixtures and compounds different?
Mixture in chemistry terminology refers to a mixture of two or more components (elements, compounds or others) in such a way that there are no specific proportions. Moreover, the constituent components retain their characteristic properties to a greater extent. Mixtures do not have fixed boiling or melting points, rather they boil or melt over temperature ranges. Mixtures can be in the solid, liquid or gas state. Compounds on the other hand are combinations of two or more elements combined in specific proportions e.g. 2 atoms of hydrogen and one of oxygen element combine to form water H2O. In forming a compound, the constituent materials lose their characteristic properties to a greater extent e.g. Hydrogen is combustible, and oxygen helps in combustion whereas water is neither combustible nor helps in combustion. Compounds, if do not have any impurities, melt and boil at fixed temperatures. Compounds also exist in the solid, liquid and gas states.
What is the oxidation number Barium?
0 in the elemental form, +2 in its compounds.
What is all matter classified as?
Answer: Matter is classified into 3 states. They are solid, liquid, gas. Matter can be also classified into materials.This are the 5 main groups of materials. They are the metals, plastics, glass, ceramic and fibre.
What is the same between compounds and mixtures?
Compounds are chemically mixed. You can't see the ingredients, elements, etc. in compounds. Compounds make a new thing. Compounds can't be separted easily. Compounds can't contain mixtures. Mixtures are not chemically mixed. You can see the ingredients, elements, etc. in the mixture. Mixtures don't create anything new. Mixtures can be separated easliy. Mixtures can contain compounds. Both mixtures and compounds are mixes of things. Both mixtures and compounds contain 2 or more elements, ingredients, etc. Hope I helped!
Describe 3 ways in which a mixture is different to a compound?
1. A mixture contain two or more compounds.2. A compound is homogeneous; a mixture may be homogeneous or heterogeneous.3. Components of a mixture can be separated by physical procedures.
What are two ways in which mixtures differ from compounds list four methods that can be used to separate mixtures?
1. Mixtures are combined by physical methods and hence can be seperated by physical methods but compounds are combined chemically hence can not be easily seperated 2. Substances in a mixture retain their normal chemistry (like Oxygen will behave like oxygen in air regardless of presence of other gases in air)(air is a mixture) that is the substances in air exist as seperate molecules while elements in compound exist as ions often times and have different behaviour,we may also add that mixtures can not be represented by a chemical formula but a compound can. Method of seperating Mixtures include: filteration,crystallization, magnetic seperation,distillation,evaporation,fractional distillation,sieving etc.
What are the similarities pure substance and mixtures?

What is matter classified as?
Matter --- Physical classification--- 1.)Solid 2.)Liquid 3.)Gas Chemical classification--- 1.)Pure sustances - *Elements *Compounds - #Inorganic compounds #Organic compounds 2.)Mixtures - *Homogeneous *Heterogeneous
What are 2 ways in which compounds form?
There are two types of compounds according to their bonding, ionic and covalent. Compounds can be divided into two with respect to their appearance, molecular compounds and crystalline compounds.
How do the four major organic compounds differ?
They differ in some of the elements from which they are made and are:- 1 Carbohydrates 2. Lipids 3. proteins 4. Nucleic Acids
What are four ways to seperate mixtures?
1. Gravity, normal or with centrifugation. 2. Chemical precipitation. 3. Chromatography. 4. Electrophoresis. 1. Gravity, normal or with centrifugation. 2. Chemical precipitation. 3. Chromatography. 4. Electrophoresis.
List 3 examples of compounds and 3 examples of mixtures?
Three examples of compounds are water, acetic acid, and nitrogen gas. They consist of two or more different elements. Three examples of mixtures are air (homogeneous), soil (heterogeneous), and salt water (homogeneous). They consist of substances that don't mix.Hope that helped! :D
Why do we not use heterogeneous compond or homogeneous compound in chemistery?
1. Only mixtures can be homogeneous or nonhomogeneous, not compounds.2. In chemistry all types of materials are used.
What are two ways cells can differ?
1.They look different.2.They have different jobs.
How do compounds differ from elements?
Compounds are made up of 2 or more elements.Compounds can be broken down into simpler substances by chemical means, but elements cannot.Compounds are made up of 2 or more elements. Compounds can be broken down into simpler substances by chemical means, but elements cannot.
