What else can I help you with?
How are the properties of a compound different from those in a mixture?
A compound has a definite composition, while a mixture's composition can vary.
If Law of constant composition true for all types of compounds?
No,Law of constant composition is valid only for compounds made from the specified isotopes of the element.
What is puresubstance?
A pure substance is a material that is composed of only one type of particle or element. It has a definite and constant composition with uniform properties throughout. Examples include elements like gold or compounds like water.
Are poptarts compounds?
A poptart is a pastry, it is an artifact constructed of various compounds. It not only has a chemical composition, it has a structure as well. It fits in your toaster.
What is the definition of a definite chemical composition?
Definite chemical composition is when a mineral is made of the same material throughout. Basically when a mineral is only made of one material all the way through, not part iron in one part and then gold in the rest.
Is fixed composition a property of a pure substance?
Yes, fixed composition is a characteristic of a pure substance. A pure substance has a uniform and definite composition, meaning it contains only one type of particle or compound throughout. This consistent composition distinguishes pure substances from mixtures, which can vary in their proportions of different components. Examples of pure substances include elements like gold and compounds like water, both of which maintain a specific ratio of their constituent atoms.
Is the composition of a substance always same?
Today this assertion is only partially valid; many nonstoichiometric compounds are known.
How was Dalton able to predict the information of multiple compounds between the elements?
Only after experiments and determination of the chemical composition.
What is a pure substane?
A pure substance is a substance that is made up of only one type of particle, either an element or a compound. It has a consistent and definite chemical composition and physical properties. Examples include elements like gold and compounds like water.
What is matter with a composition that always stays the same?
A substance that always has the same composition is called a pure substance. This means it is made up of only one type of atom or molecule, leading to consistent characteristics like melting point and boiling point. Examples of pure substances include elements like gold and compounds like water.
Why are elements and compounds considered as substances?
Elements and compounds are considered substances because they have distinct chemical properties and compositions. Elements are pure substances made up of only one type of atom, while compounds are composed of two or more different types of atoms chemically bonded together. Both elements and compounds have specific physical and chemical characteristics that distinguish them from mixtures.
Examples of pure compounds?
Some examples of pure compounds include water (H2O), table salt (NaCl), sugar (C12H22O11), and carbon dioxide (CO2). These compounds consist of only one type of molecule and have a fixed chemical composition.
