What is chemical equation give 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.
What is a chemical equation class 10?
What is a chemical Equation Class 10? Chemical Equation: Representation of chemical reaction using symbols and formulae of the substances is called Chemical Equation. In this equation, A and B are called reactants and C and D are called the products.
What is chemical reaction equation?
Chemical formulas and other symbols are used to indicate the starting materials, or reactants, which by convention are written on the left side of the equation, and the final compounds, or products, which are written on the right. An arrow points from the reactant to the products.
What are the types of chemical equation?

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 are the 5 types of chemical equations?
The five basic types of chemical reactions are combination, decomposition, single-replacement, double-replacement, and combustion.
What are the 4 types of chemical equation?
Representation of four basic chemical reactions types: synthesis, decomposition, single replacement and double replacement.
What is an equation in math?
An equation says that two things are equal. It will have an equals sign “=” like this: 7 + 2 = 10 − 1. That equation says: what is on the left (7 + 2) is equal to what is on the right (10 − 1) So an equation is like a statement “this equals that”
How do you write a class 10 chemical equation?
A chemical reaction written in the form of formula equation shows the change of reactants to products by an arrow placed between them. The reactants are written on the left side of arrow and the final substances or products are written on the right side of the arrow.
