Why is breaking down a compound into its elements consid A chemical change?
its simple, seeing as how you are breaking a compound down which consists of 2 pure substances. Means that there is a chemical change via taking one pure substance out which will inturn change it chemically and physically
Do different compounds found together but not combined chemically make up an element?
No, different compounds found together but not chemically combined do not make up an element. An element is defined as a pure substance that consists of only one type of atom, characterized by its atomic number. Compounds are formed from two or more elements that are chemically bonded together. Therefore, a mixture of compounds does not change the fundamental nature of the individual elements present.
Why would you state that sand and dirt is an example of a mixture that is not chemically combined?
Sand and dirt are considered mixtures because their components retain their individual properties and can be physically separated. Unlike a chemical compound, where elements are chemically bonded and cannot be separated without a chemical reaction, the particles in sand and dirt simply coexist without undergoing any chemical change. This means that the composition can vary, and the original substances remain intact, highlighting the nature of a physical mixture.
What substance can only be broken down by chemical change?
A substance that can only be broken down by chemical change is a compound. Compounds are made up of different elements chemically bonded together, and breaking these bonds requires a chemical reaction. Physical changes, such as melting or dissolving, cannot break compounds down into their individual elements.
What is the process in which elements change to other elements by emission of ionizing particles?
Radioactive decay.
How is a compound different from a mixture?
solids , liquids , and gases can form compounds
How does the mouth physically change food in the digestive system?
It mechanically chews it, making the particles smaller and easier to chemically digest.
How many atoms do elements have in a liquid phase?
The amount of atoms stay the same. The element does not change chemically only physically.
Which two substances cannot be broken down by chemical change?
Two substances that cannot be broken down by chemical change are elements and compounds. Elements are fundamental building blocks of matter that cannot be broken down into simpler substances by chemical reactions. Compounds are made up of two or more different elements chemically bonded together in fixed ratios, and they also cannot be broken down into simpler substances by chemical reactions.
How are compounds different from mixtures?
With a compound, a chemical change takes place. With a mixture, a physical change takes place. A compound is made when atoms of two or more elements bond in a chemical reaction. The reaction that makes a compound is difficult to undo. Mixtures can be separated using physical or mechanical means.A compound is a substance whose individual pieces or molecules are made from more than one type of Atom. A mixture can only arise from the combining, usually in water, of many, or at least several, different [types of] compounds.The elements in a compound have the same proportions by mass or numbers of atoms to one another, whenever and wherever the compound is found. The elements in a mixture have no particular constant proportions to one another in different examples of a mixture. Also, the constituents of a mixture can, at least in principle, be separated from one another without changing the chemical nature of any constituent of the mixture, but the atoms in a molecule of a compound can not be separated from one another without changing their chemical properties.A mixture is 2 or more elements or compounds that are blended without combining chemically. Each part of the matter in a mixture keeps their own identity. Mixtures can be easily separated.A compound is two or more elements chemically combined, they do not keep their identity and they are not easily separated.Compound: Salt-Both sodium and chlorine are poisonous; their compound, table salt - NaCl - is essential to lifeMixture: Kool-Aid is a mixture because you can easily identify the powder, sugar, and water.Compounds are composed of chemically bonded substances; Mixtures are composed of substances that are not bonded chemically.A mixture can be a mix of two substances that can be separated from each other physically. A compound is two (binary) or more (trinary) elements that are chemically bonded together. a mixture is combination of many different elements!A mixture is two substances combined physically, whereas a compound is two substances chemically combined.A mixture is a combination of compounds or elements that are not chemically bonded and do not react with each other, while a compound is when two or more elements or compounds are chemically bonded with each other to produce a new substance. E.g. H2O is a compound because it is comprised of 2 Hydrogen and Oxygen atoms. An example of a mixture is when ethene (C2H4) burns in air to produce 2 Carbon Dioxide (CO2) molecules and 2 Water (H2O) molecules. Since the ethene burned in air it has separated the bonded to produce two new substances which are not bonded together, thus it is a mixture.Mixtures are substances which contain components not chemically bonded to each other. Mixtures can be separated without chemical reactions. On the other hand, compounds are pure substances which can only be separated into their component elements chemically, since they are chemically bonded to each other.The different substances are not chemically joined together. Each substance in the mixture keeps its own properties. The compound has properties different from the elements it contains. Each substance is easily separated from the mixture.Mixture - A physical blend of two or more substances that are NOT chemically combined.Compound - A substance that contains two or more elements CHEMICALLY combined in a fixed proportion.Compound is chemically combined, mixture is not chemically combined. Cake would be a compound because all of the ingredients are together to make batter you cannot see the individual components (eggs, flour, sugar, etc). Trial mix would be a mixture because you can see every individual item (m&m, peanuts, raisins, etc.)A mixture contain two or more compounds. A compound has only one type of specific molecule.A compound is 2 or more types of elements that have been chemically bound to form a new substance while a mixture is 2 or more atoms of different types that are mixed together without being chemically bound.A compound is a substance in which atoms of different elements are chemically held to one another. A mixture is a substance made by combining two or more different materials in such a way that no chemical reaction occurs. A mixture can usually be separated back into its original components, a compound can not. CompoundsCompounds are pure substances.They are made up of two or more elements combined chemically.The constituents of a compound are present in a fixed ratio.Compounds have fixed properties. For example, a particular compound will have fixed temperatures at which it melts and boils.A compound can have properties different from its constituents, as a new substance is formed when the constituents are chemically combined.The constituents of a compound can be separated only by chemical methods.MixturesMixtures are impure substances.They are made up of two or more substances mixed physically.The constituents of a mixture are present in varying ratios.Mixtures do not have fixed properties. Their properties depend on the nature of their components and the ratios in which they are combined.In mixtures, no new substance is formed. The properties of a mixture are the same as the properties of its constituents.The constituents of a mixture can be separated easily by physical methods.A mixture is a combination of compounds or elements that are not chemically bonded and do not react with each other, while a compound is when two or more elements or compounds are chemically bonded with each other to produce a new substance. E.g. H2O is a compound because it is comprised of 2 Hydrogen and Oxygen atoms. An example of a mixture is when ethene (C2H4) burns in air to produce 2 Carbon Dioxide (CO2) molecules and 2 Water (H2O) molecules. Since the ethene burned in air it has separated the bonded to produce two new substances which are not bonded together, thus it is a mixture.
What is to change chemically?
Chemical change refers to a process where substances undergo a chemical reaction, resulting in the formation of new substances with different chemical properties than the original ones. This can involve the breaking or forming of chemical bonds, resulting in a change in the composition and structure of the substances involved. Examples include combustion, digestion, and rusting.
Why is the term compound used to refer to the reactant and the term substances is used to refer to the products?
The term compound is used for reactants because they are typically made up of two or more elements chemically bonded together. After a chemical reaction, these compounds undergo a change and form different substances, which are referred to as products. Substances is a more general term that encompasses elements, compounds, and mixtures.
