The question is incomplete, here is the complete question:

Which formula equation shows a reversible reaction?

A:

B:

C:

D:

The reversible reaction is

Explanation:

Reversible reaction is defined as the reaction in which the products formed react together to give the reactants back. For general reversible chemical equation:

Irreversible reaction is defined as the reaction in which the reactants only lead to products and the reaction do not proceed back. For general irreversible chemical reaction:

For the given options:

The reaction having an equilibrium sign between the reactants and products is equation C.

Hence, the reversible reaction is

answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.
