The chemical formula of an emerald is Be3Al2(SiO3)6. An emerald can be described as
Answer 1
The correct statement is a pure substance because it is a compound. Explanation: A pure substance is defined as the substance formed by the same atom or different atoms which are chemically combined in a fixed mass ratio. Compounds and elements are considered pure substances. Impure substances are defined as substances that do not have a defined chemical composition. They are basically mixtures of substances that are not combined chemically. A compound is a substance that is formed by two or more different types of atoms when they combine chemically. An element is defined as a substance that has only one type of atoms. Emerald is a compound with the chemical formula . This is considered a pure substance. Therefore, the correct statement is a pure substance because it is a compound.
answer 2
An emerald can be described as a composite because it is made up of many different elements. Explanation:
answer 3
An emerald can be described as a pure substance
because it is a composite.
answer 4
An emerald can be described as a pure substance because it is a compound. it is a pure substance because it is an element. It is an impure substance because it is chemically combined, an impure substance because it is a mixture. Explanation:
Answer 5
The answer is: a pure substance because it is a compound.
Pure substance consists of one type of atom or one type of molecule, it has a definite and constant composition with distinct chemical properties. Emerald (beryl) is a chemical compound (aluminum beryllium cyclosilicate) with the chemical formula Be₃Al₂(SiO₃)₆. Pure beryl is colorless.
Answer 6
I think the best answer
is the first option. An emerald can be described as a pure substance
because it is a composite. A pure body is defined as matter with
defined and constant composition throughout the sample. For this case,
Emerald is chemically held together so anytime you get a sample it
would still be emerald.
Answer 7
An emerald can be described as a pure substance because it is a compound. Compounds are considered pure substances because they cannot be broken down by any mechanical or physical process. A compound is a molecule made up of two or more atoms of the same or different elements. Water is also considered a pure substance. It is made up of one oxygen atom and two hydrogen atoms. A water molecule cannot be separated by any mechanical or physical process.
Answer 8
I think the best answer is the first option. An emerald can be described as a pure substance because it is a compound. A pure substance is defined as a material having a definite and constant composition throughout the sample. In this case, the emerald is chemically held together, so no matter when you get a sample, it will still be emerald.
Answer 9
The correct answer to the question posed and illustrated above is: “a pure substance because it is a compound”. The chemical formula of emerald is Be3Al2(SiO3)6. An emerald can be described as a pure substance because it is a compound.
Answer 10
Emerald is a compound composed of beryllium, aluminum, silicon and oxygen with the formula Be3Al2(SiO3)6 Explanation:

The chemistry of living systems representing all chemical reactions is calledAnswer 1The chemistry of living systems which represent all chemical reactions is called metabolism. Metabolism is defined as a set of all chemical reactions within an organism. The objectives of metabolic processes are to convert food energy into energy necessary for cellular processes, to synthesize the constituent elements of proteins, lipids, nucleic acids and certain carbohydrates (macromolecules) and to eliminate nitrogenous waste products. Catabolism and anabolism are part of metabolism that work together to maintain functions within the cell.Catabolic processes (breakdown of macromolecules) are necessary for the release of energy (usually in the form of ATP) which is then used in the anabolism-synthesis of compounds needed by the cell.answer 2I needanswer 3what is the complaint?

What is the total number of valence electrons in a germanium atom in the ground state?
What is the total number of valence electrons in a ground state germanium atom? (1) 22 (3) 32(2) 2 (4) 4Answer 14+ Explanation: Germanium, an element of the fourth group of the periodic table, has a valence of 4, ie 4 electrons in its outermost shell.answer 2D.4 Explanation: The periodic table of elements shows Ge, Germanium, with an electron configuration of 2-8-18-4. Valence electrons are the electrons of the outermost principal energy level of an atom. Germanium has 4 valence electrons.answer 3The atomic number Ge is 32 and the condensed electron configuration is - [Ar] 3d¹⁰ 4s² 4p² valence electrons are electrons in the outermost energy shell involved in chemical bonding the number of electrons in the 4th energy shell is 4 electrons by definition valence electrons are electrons in the outermost energy layer of the energy layer The outermost layer of Ge is the 4th energy layer, so the valence electrons of a ground-state germanium atom are located in the (4th) fourth layeranswer 4Fourth shell. I hope this helps you.Answer 5It would be on the fourth shell.Answer 6The valence electrons of a ground state germanium atom are located in the fourth shell.Answer 7The answer is (4) – 4.
