At sufficiently high temperatures and low pressures, all elements are composed of atoms. At standard temperature and pressure, some elements are composed of molecules, usually diatomic molecules, as with nitrogen, hydrogen, oxygen, and all the halogens.
Compounds are composed of atoms of different elements chemically bonded in definite proportions. The components of mixtures are not chemically combined and they do not have definite proportions.
MixtureAnswer:They're more of an ecosystem. A number of independent organisms living together (People, microbes, intestinal flora and fauna, mites in the eyebrows, worms, parasites). Each organism is made of molecules containing various compounds. A lot of the traffic in food and oxygen is done by solutions (mixtures) like blood, bile, insulin, lymphatic fluids and mucous.
The overall definition that includes mixtures, compounds, and elements is matter. Matter refers to anything that has mass and takes up space. Mixtures are combinations of different substances that can be physically separated, compounds are substances composed of two or more elements chemically bonded, and elements are pure substances composed of only one type of atom.
It's not the atoms that change, it is the molecules... In short, the molecules(elements) can share, give, or take electrons from other molecules(elements).
No they are not.
Oh, dude, compounds are like those fancy molecules where the atoms are all bonded together in specific ratios, while mixtures are just a bunch of stuff hanging out together without any commitment. Compounds are like the serious relationships of chemistry, while mixtures are more like a chaotic party where everyone's just doing their own thing. So, like, compounds are all structured and organized, while mixtures are just a hot mess.
Yes, all the mixtures contain compounds or elements.
No. Elements, compounds and mixtures are 3 different terms.
magnesium and oxygen are elements. They are not compounds
Mixtures are composed of two or more substances that are physically combined and can be separated by physical means, while compounds are composed of two or more elements chemically bonded together and cannot be easily separated. Mixtures can have varying compositions and properties throughout, while compounds have a fixed composition and consistent properties.
Elements and compounds are pure substances. Elements are composed of only one kind of atom and compounds are composed of two or more elements that are chemically combined. Mixtures are not pure substances, as they are composed of two or more components that are not chemically combined.
Elements and atoms are mainly the same. Molecules are made up of atoms and chemical bonds are bonds that combine the atoms together to make molecules. Compounds are just about the same as molecules only are made up of molecules like how molecules are made of atoms. Substances can relate to anything, and mixtures are many compounds and molecules mixed together.
