How to teach chemical formulas and equations
The common names and formulas of chemical compounds is a very relevant area of study for every competitive exam including SSC and it is important for the aspirants to develop a fair idea on this subject. In this article, we are discussing the following topics. A chemical compound is a chemical substance composed of many identical molecules composed of atoms from more than one element held together by chemical bonds. There will be a fixed ratio for a chemical compound determining the composition of it. For example, water H2O is a compound consisting of two hydrogen atoms bonded to an oxygen atom. The ratio of each element is usually expressed by a chemical formula. Water, carbon dioxide and table salt are three examples for chemical compounds.
Here are printable chemistry worksheets in pdf format. The second worksheet asks for the chemical name based on the chemical formula. Answer keys are provided separately. Formula Worksheet Set 1. Formula Worksheet Set 2. In order to complete these worksheets, you may wish to review the rules for naming ionic compounds and covalent compounds.
Glossary of chemical formulae
Chapter 7 - Chemical Formulas and Chemical Compounds Section 1 Chemical Names and Formulas The chemical formulas tells the number of atoms of each element in a compound. Percent Composition and Molecular Formula Worksheet. This is just one of the solutions for you to be successful. Label each of the following statements as True or False: True a. D: chemists use systematic methods for naming compounds and for writing chemical formulas. Though these formulas are found to be very hard to learn and understand, very necessary to solve the reaction. Assign the oxidation number to the specified element in each of the following examples: 4 a.
Chemistry is said to be a subject mostly comprising of reactions along with formulas. We come across various chemical substances in our daily life. Some of the substances we use in our house such as the staples present in the medicine cabinet comprise chemical substances. Chemical Formula in Chemistry is like a shorthand used to represent the elements in a compound. The Periodic Table has elements along with the symbols. These Chemical symbols are used for representing different individual elements like H is hydrogen, O for oxygen, Ca for calcium, Na for Sodium and so on. Molecular Formula : The molecular formula gives you the number of elements present in a compound.
Ionic compound is represented by a formula unit, the lowest ratio of atoms in the compound. Page Naming Ionic Compounds. (positive metal ion +.

The empirical and molecular formulas discussed in the preceding section are precise and informative, but they have some disadvantages. First, they are inconvenient for routine verbal communication.
These are limited to a single typographic line of symbols, which may include subscripts and superscripts. A chemical formula is not a chemical name , and it contains no words. Although a chemical formula may imply certain simple chemical structures, it is not the same as a full chemical structural formula.
