A compound is a pure substance that contains two or more elements chemically combined. E.g, sodium chloride, carbon dioxide.
A molecule is a group of at least 2 or more atoms chemically combined by covalent bonds. E.g, oxygen (O2), chlorine gas (Cl2)

What is the difference between a substance composed of a mixture of different atoms and a compound composed of molecules?
A substance composed of a mixture of different atoms contains different types of atoms that are physically mixed together but not chemically bonded. In contrast, a compound composed of molecules consists of specific atoms chemically bonded together in fixed ratios to form distinct molecules with unique properties.
What is the difference between formula mass and the molecular mass of a compound?
1 mol is equal to 6.02214179(30)×1023 molecules of the substance. The molecular weight is how much grams these molecules (6.02214179(30)×1023) weigh. Meaning g/mol.
Why do a definite number of molecules of water combine with a definite amount of a compound in forming a hydrate?
In a hydrate, the water molecules combine in a specific ratio with the compound due to the structural arrangement and chemical bonding between the water molecules and the compound. This specific ratio ensures the formation of a stable crystalline structure, where each water molecule occupies a specific location in the compound's lattice. This results in a fixed number of water molecules combining with a definite amount of the compound to form a hydrate.
What makes a compound insoluble?
A compound is insoluble when the forces of attraction between its ions are stronger than the forces of attraction between the compound and the solvent molecules. This means that the compound does not readily dissociate into its ions in the solvent, preventing it from dissolving. Common reasons for insolubility include the presence of strong intermolecular forces, such as in ionic compounds with large cations and anions, or the lack of compatible interactions with the solvent molecules.
What is the connection between molecules and compounds?
A compound is a substance formed by the chemical bonding of two or more elements in specific proportions. A molecule is the smallest portion of a compound.
What is the difference between a hydrous compound and an anhydrous?
A hydrous compound contains water molecules in its crystal structure, while an anhydrous compound does not contain any water molecules. Hydrous compounds can lose water when heated, converting into an anhydrous form.
What is the difference beteween molecule and compound?
A molecule is the smallest unit of a substance that retains all the properties of that substance, while a compound is a substance made up of two or more different elements chemically bonded together. All compounds are molecules, but not all molecules are compounds.
What is the difference between a compound and a molecule?
A compound is a substance made up of two or more different elements chemically bonded together, while a molecule is the smallest unit of a compound that retains the chemical properties of that compound. In simpler terms, all compounds are molecules, but not all molecules are compounds.
What is the difference between elemetns and molicules?
an element is the basic part, molecules are the simplest unit that have the features and chemical make up of a compound.
What is the main difference between a molecule and compound?
A molecule is formed when two or more atoms join together chemically. A compound is a molecule that contains at least two different elements. All compounds are molecules but not all molecules are compounds.

What is the difference between a molecule and a compound in terms of their structure and composition?
A molecule is a group of atoms bonded together, while a compound is a substance made up of two or more different elements chemically bonded together. In other words, all compounds are molecules, but not all molecules are compounds.
What is the difference between a molecule and a compound in terms of their chemical composition and structure?
A molecule is a group of atoms bonded together, while a compound is a substance made up of two or more different types of atoms bonded together. In other words, all compounds are molecules, but not all molecules are compounds.
What is the difference between an identical compound and its enantiomer?
An identical compound and its enantiomer have the same chemical formula and structure, but they are mirror images of each other. They differ in their spatial arrangement of atoms, which can result in different properties, such as how they interact with other molecules.
What is the difference between a substance composed of a mixture of different atoms and a compound composed of molecules?
A substance composed of a mixture of different atoms contains different types of atoms that are physically mixed together but not chemically bonded. In contrast, a compound composed of molecules consists of specific atoms chemically bonded together in fixed ratios to form distinct molecules with unique properties.
