Do elements that combine in changing ratios form mixtures?
When elements combine in changing ratios, they form compounds rather than mixtures. Mixtures are made up of different substances that are not chemically bonded together, while compounds are formed by chemical bonding between elements in specific ratios.
In what form are you using heterogeneous mixtures?
Schools often want to have heterogeneous groups of students.
What do you find least of in nature elements compounds or mixtures?
Pure elements are found least in nature compared to compounds and mixtures. Most elements exist bonded to other elements to form compounds or mixed with other substances to form mixtures in nature. Pure elements are less common due to their tendency to react and combine with other elements.
What can be classified as a substance?
A substance can be classified as a form of matter that has a specific chemical composition and properties. This includes elements, compounds, and mixtures. Examples of substances include water (H2O), salt (NaCl), and air (a mixture of gases).
Is petrol heterogeneous?
Yes, petrol is considered a heterogeneous mixture because it is composed of various hydrocarbon compounds with different boiling points and properties. These components do not combine chemically, but rather exist together in a dispersed form.
When particles of a mixture that are not joined together what is this called?
When particles of a mixture are not joined together, it is called a heterogeneous mixture. In a heterogeneous mixture, the individual components remain distinct and do not combine to form a new substance. Examples of heterogeneous mixtures include a mixture of oil and water or a combination of sand and iron filings.
When elements and compounds combine to form new compounds the reaction is described in a?
When elements and compounds combine to form new compounds the reaction is described in a chemical equation.
How do the parts of an atom combine to form compounds and mixtures?
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).
Is arsenic heterogeneous or homogeneous?
Arsenic is considered a homogeneous substance when it exists in its pure elemental form, as it has a uniform composition throughout. However, in nature, arsenic can be found in various compounds and mixtures, which may be heterogeneous depending on their composition and distribution. Therefore, the classification can depend on the specific form and context of arsenic being referred to.
What do elements combine to form?
Elements combine to form compounds through chemical reactions. These compounds have different properties than their individual elements, resulting in a wide range of substances found in nature and synthesized in laboratories.
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!
which of the following is NOT true about elements when they combine to form compounds a. atoms of elements combine to form moleculesb?
yeah it is
