What information is shown in a chemical equation?
A chemical equation will tell you the formulas and symbols of the reactants and products. A chemical equation can show the physical state of a substance, whether it is a solid, liquid, gas, or in solution.
What is the definition of chemical equation in science?
a representation of a chemical reaction using symbols of the elements to indicate the amount of substance, usually in moles, of each reactant and product.
Does a chemical formula describes a chemical reaction?
A chemical equation describes a chemical reaction. Reactants are starting materials and are written on the left-hand side of the equation. Products are the end-result of the reaction and are written on the right-hand side of the equation.
Why are chemical equations useful?
Explanation: Chemical equations show us the products of the reactions and how they are formed. They are useful to predict the products of a reaction. which is a balanced equation, and obeys the law of conservation of mass.
What two types of chemical equation are there?

What is a chemical equation explain with an example?
The method of representing a chemical reaction with the help of symbols and formulae of the substances involved in it is known as chemical equation. For example, zinc metal reacts with dilute sulphuric acid to form zinc sulphate and hydrogen gas.
How do you write a chemical equation?
Key PointsIn a chemical equation, the reactants are written on the left, and the products are written on the right.The coefficients next to the symbols of entities indicate the number of moles of a substance produced or used in the chemical reaction.
What is chemical reaction and its types?
Table of Content
| Types of Chemical Reactions | Explanation | General Reaction |
|---|---|---|
| Combination reaction | Two or more compounds combine to form one compound. | A + B → AB |
| Decomposition reaction | The opposite of a combination reaction – a complex molecule breaks down to make simpler ones. | AB → A + B |
