What is a compound represented by?
Compounds are represented by chemical formulas. Elements in a compound are represented by chemical symbols, and the ratio of different elements is represented by subscripts. There are different rules for writing the chemical formulas for ionic and covalent compounds.
What are 2 examples of compounds?
Examples of compounds include table salt or sodium chloride (NaCl, an ionic compound), sucrose (a molecule), nitrogen gas (N2, a covalent molecule), a sample of copper (intermetallic), and water (H2O, a covalent molecule).
What is classified as a compound?
Matter can be classified into two broad categories: pure substances and mixtures. A substance that can be broken down into chemically simpler components (because it has more than one element) is a compound. For example, water is a compound composed of the elements hydrogen and oxygen.
What are the 2 classes of matter Brainly?
Answer: Matter can be broken down into two categories: pure substances and mixtures. Pure substances are further broken down into elements and compounds. Mixtures are physically combined structures that can be separated into their original components.
What is difference between a substance and a mixture Brainly?
Answer: Mixtures are physically combined structures that can be separated into their original components. A substance is composed of one type of atom or molecule.
What are the properties of pure substances Brainly?
Pure substances are generally made up of only a single kind of atom or particle, has a definite structure, constant chemical composition and have a fixed boiling and melting poin-ts.
What are the properties pure substances?
Characteristics and Properties Of Pure Substances
- Pure substances are mostly homogeneous in nature containing only one type of atoms or molecules.
- These substances mainly have a constant or uniform composition throughout.
- The substances have fixed boiling and melting points.
What is a pure substance in Brainly?
Answer: Pure substances are substances that are made up of only one kind of particles and has a fixed or constant structure. Pure substances are further classified as elements and compounds. kvargli6h and 215 more users found this answer helpful. Thanks 150.
What is the pure substances of boiling point Brainly?
Answer. Answer: The boiling point of a pure substance is the temperature at which the substance transitions from a liquid to the gaseous phase. The boiling point at a pressure of 1 atmosphere is called the normal boiling point.
What are the components of water Brainly?
Water molecule is composed of two elements: hydrogen and oxygen or, more precisely, two hydrogen atoms (H2) and one oxygen atom (O). Hydrogen and oxygen are gases at room temperature.
What is a pure substance in science?
A substance that has a fixed chemical composition throughout is called a pure substance such as water, air, and nitrogen. A pure substance does not have to be of a single element or compound.
