Some chemical reactions are reversible. What does this mean?

A chemical reaction can go both ways. Products can become reactants and vice-versa
A chemical reaction can be reversed once using an extremely high amount of energy
A chemical reaction can only go one way, but the order of the reactants is reversed in the equation
A chemical reaction which is written in reverse, with the reactants on the right and the products on the left

Which of the following symbols is used to represent a reversible reaction?

[question number = 02.8] Use the following words to fill in the blanks:

Open, closed, active, dynamic, static

- equilibrium only occurs in systems.
- In an system gases can escape so equilibrium would not be achieved.

Which of the following explains dynamic equilibrium?

Dynamic equilibrium is when a reversible reaction achieves a balance, where the forwards and backwards reactions happen at the same rate
Dynamic equilibrium is when one reactant is added in excess and the other is completely converted to the products.
Dynamic equilibrium is before a non-reversible reaction is started
Dynamic equilibrium only happens in open systems and describes the escape of the products as gases
