what does chemical equations means ?
Answers
Answer:
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.
What is a Chemical Equation?
➡Chemical equations are symbolic representations of chemical reactions in which the reactants and the products are expressed in terms of their respective chemical formulae.
➡They also make use of symbols to represent factors such as the direction of the reaction and the physical states of the reacting entities.
➡Chemical equations were first formulated by the French chemist Jean Beguin in the year 1615.
➡Chemical reactions can be represented on paper with the help of chemical equations, an example for which is represented below (for the reaction between hydrogen gas and oxygen gas to form water).
2H2 + O2 → 2H2O
➡It can be observed in the example provided above that the reacting entities are written on the left-hand side whereas the products that are formed from the chemical reactions are written on the right-hand side of the chemical equation.
➡It can also be observed that there are coefficients assigned to each of the symbols of the corresponding reactants and products.
➡These coefficients of entities in a chemical equation are the exact value of the stoichiometric number for that entity.
Answer:
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.
