Question

Explain the meaning of the symbols as they are used in this expression.

Answer 1

Answer:

• A, B, C and D are: elements or molecules
• A and B are: reactants
• C and D are:  products

Explanation:

The expression "A + B <--> C + D" represents a chemical equation. A chemical equation represents the "mixture" of molecules or elements that will react and form other molecules and elements, so we can say that A, B, C and D represent molecules or elements.

But not only that. In a chemical equation, the elements and molecules that are before the symbol "<-->" represent the reagents in the equation. Therefore, A and B are the reagents. The elements or molecules found after the symbol "<-->" are the products of the reaction. Therefore, C and D are the products.

Answer 2

Question 1) A and B are:  Reactants

Question 2) C and D are:  Products

It is a chemical process in which reactants  A and B react as represented by the (+) symbol, producing Product  C and D

<--> is the sign of reversible reaction that means A + B can form C and D, Similarly C and D can form A and B
