Question

What do the following symbols mean in a chemical equation?
A. $\to $
B. $\xrightarrow{\vartriangle }$
C. (s)
D. (l)
E. (aq)

Answer 1

Hint: Before solving this question, we should first know what are symbols and then we can understand one by one what each symbol represents. Symbols are representative of various chemicals, elements, and various actions in chemistry. If someone wants to pursue chemistry. They should be familiar with all the symbols.

Complete step-by-step answer:
The first symbol is $\to $
This symbol shows that the reactants have reacted and have gone through some processes and have formed the products. After undergoing a chemical process, They are changed somewhere.
 The second symbol is $\xrightarrow{\vartriangle }$
This symbol represents that the heat has been applied and the reaction is being accelerated to form the products.
The third symbol is (s)
This symbol represents the state of the compound i.e Solid in the equation.
 The fourth symbol is (l)
This symbol represents the state of the compound i.e liquid in the equation.
 The fifth symbol is (aq)
This symbol represents that the substance is dissolved in the water and is in an aqueous state.

Note:
The coefficients that are seen in the chemical equations are used to represent the amount of that particular substance present in the equation. It can show the relative no. of the molecule or relative no. of moles in the equation. If nothing is shown then we assume it to be one. Symbol (g) represents the state of the substance i.e Gas in the equation.
