Define formula of a compound.
Give examples.
Answers
Answer:
A compound is a substance made up of a definite proportion of two or more elements. A chemical formula tells us the number of atoms of each element in a compound. ... Let's take a look at the chemical formula of sucrose: there are 12 carbon (C) atoms, 22 hydrogen (H) atoms and 11 oxygen (O) atoms.

Answer:What is a Compound?
When two or more elements chemically combine in a fixed ratio by mass, the obtained product is known as a compound. Compounds can be defined as substances consisting of 2 or more different types of elements in a fixed ratio of its atoms. When the elements combine, some of the individual property of the elements is lost and the newly formed compound has new properties.
Chemical Formula: Compounds are represented by their chemical formula. A chemical formula is a symbolic representation of the proportions of atoms that constitute a particular chemical compound.
The chemical formula of water is H2O which shows two atoms of hydrogen and one atom of oxygen have combined to form one molecule of H2O. The chemical formula for common salt is NaCl which shows one atom of sodium and one atom of chlorine combine to form one molecule of NaCl.
1. Types Of Compounds
Compounds can be classified into two types, molecular compounds, and Salts. In molecular compounds, atom binds each other through covalent bonds. In salts, it is held together with ionic bonds. These are the two types of bonds out of which every compound is made of.
2. Example Of Compounds
Example of compounds includes water (H2O), Hydrogen Peroxide (H2O2), etc. You could see water’s chemical formula, it says it has 2 atoms of Hydrogen combined with 1 atom of oxygen and in hydrogen peroxide, it has 2 atoms of hydrogen and two atoms of oxygen.
Similarly, an example of salt would be the table salt (NaCl) which has 1 atom of sodium and one atom of chlorine.
