Explain the meaning of the symbols as they are used in this expression.
Dmitrij [34]

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.
