A substance made of two or more elements chemically combined in a specific proportion is called a compound. A substance composed of two or more elements combined chemically in a fixed proportion by mass is called a compound. A chemical compound can be held together by a covalent bond or an ionic bond.
Imppure matter is a substance which contains a mixture of elements- 1. It does not have fixed melting point, boiling point or density 2. t gives more than one spot whenn analysed by chromatography
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). Trail mix would be a mixture because you can see every individual item (m&m, peanuts, raisins, etc.)
An element is a pure substance made up of only one type of atom, such as oxygen or gold. A compound is a substance made up of two or more different elements chemically bonded together, like water (H2O) or salt (NaCl).
A compound is a substance that contains 2 or more different elements combined chemically. if you mean Ne, then no, because that is Neon (which is one element) But if you mean NE, then yes becaus, N is 1 atom, and E is another.
Water is a compound composed of two elements, hydrogen and oxygen, bonded together chemically to form a single substance with the chemical formula H2O.
This is a molecule.
The water molecule contains two different elements chemically combined, which makes it a compound. A compound is a pure substance that contains two or more different elements chemically combined.
In chemistry, a compound is a substance made up of two or more different elements that are chemically bonded together. These elements combine in fixed ratios to form a unique substance with distinct properties. Examples of compounds include water (H2O) and sodium chloride (NaCl).
a compound is a substance that contains two or more elements chemically combined in a fixed proportion while mixture is a physical blend of two or more substances that are not chemically combined
This is an oxide.
This is an oxide.
Yes. A mixture contains different substances that are not chemically combined with one another. The parts of a mixture can be separated through physical means.
Calcium Carbonate is a compound as it contains 3 different elements (calcium, carbon and oxygen) that are chemically combined.
Non-metal oxide contains a non-metal chemically combined with oxygen.
A compound is defined as a pure substance made up of two or more types of elements (atoms) chemically combined in a fixed proportion, and it can be further subdivided into simpler substances by chemical means only.A molecule is the smallest part of a compound, whose properties are the same as those of the compound.
