Question

What is the chemical equations and skeletal Equations?

​

Answer 1

Answer:

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.

Skeleton Equations are the equations in which there is only chemical formula of reactants and products but no state mentioned and no balancing of atoms on either side of Equation done.

For example: Mg + O2 → MgO, it’s a skeleton equation.

Here, the only thing mentioned is the chemical formula of reactants: Magnesium(Mg), oxygen (O2) and products: Magnesium Oxide(MgO).

Balanced Equation is like: 2Mg(s) + O2(g) → 2MgO(s).
