What contains 2 or more elements chemically combined?
A compound contains two or more elements chemically combined. In a compound, the elements are bonded together in fixed proportions by chemical bonds. Examples include water (H2O) and carbon dioxide (CO2).
Are the proportions of a compound fixed or not fixed?
The proportions of elements in a compound are fixed, meaning that a specific compound will always have the same ratio of elements by mass. This fixed ratio is determined by the chemical formula of the compound.
What is meant by fixed ratio of atom in a molecule?
A fixed ratio of atoms in a molecule refers to the specific arrangement and number of atoms that are bonded together to form a compound. This ratio is determined by the chemical formula of the substance and remains constant for that particular molecule. For example, in water (H2O), there is always a fixed ratio of 2 hydrogen atoms to 1 oxygen atom in each molecule.
How is a homogeneous mixture different from a homogeneous compound?
In a compound the component elements are chemically bonded together in a fixed ratio. In a homogeneous mixture the components are not chemically bonded together and the ratio can vary.In a compound the component elements are chemically bonded together in a fixed ratio.In a homogeneous mixture the components are not chemically bonded together and the ratio can be varied.
The composition of a mixture can vary unlike a compound why is that?
Because a mixture means that it contains a mix of substances. And you can choose to mix different amounts (solutions), instead of where in order to create that compound, a specific ratio of elements are required. If the ratio is incorrect, the result will not equal the same compound.
What material contains components in a fixed ratio?
A compound is a material that contains components in a fixed ratio. In chemical terms, compounds are formed when two or more elements chemically bond together, resulting in a substance with specific properties and a defined composition. For example, water (H₂O) is a compound made up of two hydrogen atoms and one oxygen atom in a fixed ratio of 2:1.
How is the ratio of components in a mixture different from the ratio of element in a compound?
The ratio in mixtures can be varied, within reason, with little impact on the properties of the mixture. The ratio in compounds is fixed.
What materials that are made up of two of more pure substance not chemically combined the materials do not have a fixed ratio of elements and can be separated into their by physical means?
Materials composed of two or more pure substances that are not chemically combined are known as mixtures. These mixtures do not have a fixed ratio of components and can be separated by physical means, such as filtration, distillation, or chromatography. Examples include air, salad, and sand and salt mixtures. Unlike compounds, the individual substances in a mixture retain their own properties.
How is a homogenous mixture different from a compound?
In a compound the component elements are chemically bonded together in a fixed ratio. In a homogeneous mixture the components are not chemically bonded together and the ratio can vary.In a compound the component elements are chemically bonded together in a fixed ratio.In a homogeneous mixture the components are not chemically bonded together and the ratio can be varied.
Why can iron sulfide be classified as a compound?
Because it contains two elements that are chemically bonded together in a fixed ratio.
What is a fixed ratio?
a ratio that was at first incorrect but has been fixed
What are two or more different atoms are combined in definite proportion?
A simple definition is: a chemical compond has the elemental components in a fixed ratio.
Contains two or more elements in a fixed ratio?
A chemical compound that has a set number of atoms for each element. E.g. water H2O has the fixed ratio of 2:1, that is 2 hydrogen atoms to 1 oxygen atom, carbon dioxide CO2 has a fixed ratio of 1:2 (1 carbon atom to 2 oxygen atoms). It has to be fixed as if it isn't it makes a new compound/chemical.
What has definite ratio of components?
A compound has a definite ratio of components.
what is meant by fix ratio of atom in molecule?
1 ratio 5 is the fixed ratio of atom in a molecules...
Is matter a homogenous?
no homogeneous substances is not uniform as it contains mixture of many substances and therefore all particles cannot remain in fixed ratio.
Is chunky spaghetti sauce an element compound or mixture?
Chunky spaghetti sauce is absolutely a mixture because its components are not mixed in a fixed ratio by mass
