What is the question of a molecule and a compound?
The question of a molecule is the arrangement of atoms that make up the molecule, including the types of atoms and how they are bonded together. A compound is a substance made up of two or more different types of atoms bonded together in a specific ratio.
How does changing the ratio of nitrogen atoms and oxygen atoms change the compounds?
Changing the ratio of nitrogen and oxygen atoms can result in different compounds being formed. For example, nitrogen dioxide (NO2) and nitric oxide (NO) are both nitrogen-oxygen compounds with different ratios of N to O atoms. Changing this ratio can affect the properties of the compounds, such as their reactivity and toxicity.
What statements about compounds is true?
Compounds are formed when two or more different elements are chemically bonded together. They have a fixed ratio of atoms and cannot be separated by physical means. Compounds exhibit unique and distinct properties from their component elements.
A substance composed of two or more kinds of atoms always in the same ratio?
This substance is called a compound. Compounds are formed when atoms of different elements chemically bond together in fixed proportions. The ratio of these atoms in a compound is constant and is represented by a chemical formula.
When two or more different atom combine together in a fixed ratio they produce?
a compound. Compounds are formed when two or more different elements chemically bond together in a specific ratio, creating a new substance with unique properties. The combination of atoms in compounds follows the law of definite proportions, meaning the ratio of elements in the compound is always the same.
How are the particles different in compounds and mixtures?
In compounds, particles are chemically bonded together to form a new substance with its own unique properties, whereas in mixtures, particles are not chemically bonded and can be easily separated by physical means. Compounds have a fixed ratio of atoms, while mixtures can vary in composition.
When nitrogen and hydrogen combine what will be the ratio of hydrogen atoms to nitrogen atoms in a molecule of the resulting compounds?
In a molecule of ammonia (NH3), which forms when nitrogen and hydrogen combine, the ratio of hydrogen atoms to nitrogen atoms is 3:1.
It is possible for different covalent compounds to have the same empirical formula because empirical formulas represent?
the simplest whole-number ratio of atoms in a compound. Different covalent compounds can have the same empirical formula if they have different molecular structures that still result in the same ratio of atoms.
Is ratio of atoms is always the same in a compound?
Generally yes (the law of definite proportions); as exceptions - nonstoichiometric compounds.
Pure substances can be classified as or compounds.?
Pure substances can be classified as elements or compounds. Elements are made up of only one type of atom, while compounds are made up of two or more different types of atoms chemically bonded together in a fixed ratio.
How is a molecule different than a compound?
A molecule is two or more atoms held together by covalent chemical bonds. A chemical compound is a pure chemical substance consisting of two or more different chemical elements that can be separated into simpler substances by chemical reactions. Chemical compounds have a unique and defined chemical structure; they consist of a fixed ratio of atoms that are held together in a defined spatial arrangement by chemical bonds. Chemical compounds can be molecular compounds held together by covalent bonds, salts held together by ionic bonds, intermetallic compounds held together by metallic bonds, or complexes held together by coordinate covalent bonds
What is formed when elements of matter are chemically combined atoms compounds mixtures ions?
When elements of matter are chemically combined, they form compounds. Compounds are substances made up of two or more different types of atoms that are bonded together in a fixed ratio. In contrast, mixtures consist of two or more substances that are physically combined but not chemically bonded. Ions are charged particles that can form when atoms gain or lose electrons, but they do not represent a combination of different elements.
