What are the basic chemical equations?
A chemical equation shows the starting compound(s)—the reactants—on the left and the final compound(s)—the products—on the right, separated by an arrow. The number of atoms, molecules, or formula units of a reactant or product in a balanced chemical equation is the coefficient of that species.
What is chemical equation write two examples?
1 CH4 + O2 → CO2 + 2 H2O. Inspection of the last atom to be balanced (oxygen) shows that the right-hand side has four atoms, while the left-hand side has two. It can be balanced by putting a 2 before O2, giving the balanced equation: CH4 + 2 O2 → CO2 + 2 H2O.
What is chemical equation answer?
A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and formulae, wherein the reactant entities are given on the left-hand side and the product entities on the right-hand side with a plus sign between the entities in both the reactants and the products and an arrow that …
What is chemical equation for class 10th?
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.
Why do we write chemical equations?
– By writing a chemical equation we can know about the reactants and products involved in a chemical reaction. of atoms of a particular element involved in a reaction. – By writing a chemical equation; we get to know about the ratios of reactants and products involved in a reaction.

What are the rules for writing a chemical equation?
Rules for writing chemical equation: Certain rules have to be followed while writing a chemical equation. The reactants taking part in the reaction are written in terms of their symbols or molecular formulae on the left-hand side of the equation. A plus (+) sign is added between the formulae of the reactants.
How do you write a balanced chemical equation?
Write a balanced chemical equation for. Sodium(s) + hydrochloric acid(aq) → sodium chloride(aq) + hydrogen(g) Solution: Step 1: Convert the chemical names into chemical formulas. Place them based on the chemical equation and write the state symbols.
What is the definition of a chemical equation?
Chemical equation. A chemical equation is the symbolic representation of a chemical reaction where the reactant entities are given on the left hand side and the product entities on the right hand side. The coefficients next to the symbols and formulae of entities are the absolute values of the stoichiometric numbers.
What makes a chemical equation balanced?
A balanced chemical equation occurs when the number of the different atoms of elements in the reactants side is equal to that of the products side.Balancing chemical equations is a process of trial and error. IT FOLLOWS THE LAW OF CONSERVATION OF MASS which states that.
