Question

Select the descriptor that best describes the relationship between the "reactants" and "products"

Select the descriptor (A, B, C, D): that that best describes the relationship between the "reactants" and "products" below:

Answer 1

General guidance

Concepts and reason

Different arrows are used to represent an equilibrium reaction. Arrows are placed between reactants and products.

Fundamentals

Chemical equation use arrows to represent them.

A substance which changes into another substance is the reactant and the substance which obtained is product.

Step-by-step

Step 1 of 2

Understand which type of equilibrium arrow is used to which equilibrium.

The arrow with descriptor A is resonance arrow. The arrow with descriptor B is used to represent dynamic equilibrium, favoring reactants. The arrow with descriptor C is used to represent dynamic equilibrium, favoring products. The arrow with descriptor D is used to represent dynamic equilibrium.

Explanation

Full and double head arrow in A represents resonance structures. Long half-head arrow is used to describe if reactants favor to change into products or products favor to change into reactants. Short half-head arrow is used to describe if reactants not favor to change in products or products not favor to change into reactants.

[Hint for the next step]

Select the correct descriptor for the given reactants and products.

Step 2 of 2

The correct descriptor for the given reactants and products is B.

The descriptor B best describes the relationship between the reactants and products.

Sulfuric acid is a strong acid and more easily give up a proton (${{\\rm{H}}^{\\rm{ + }}}$). Products favor to change into reactants in this equilibrium and it is described with long half-head arrow.

Answer

The descriptor B best describes the relationship between the reactants and products.

Answer only

The descriptor B best describes the relationship between the reactants and products.
