<h3>What are equilibrium reactions?</h3>
An equilibrium reaction is a chemical reaction process in which the reactants remain in a steady and stable condition both previously(reactant) and after the reaction is completed(product).
A reaction is considered to be at thermodynamic equilibrium when a reaction meets all three categories of equilibrium;
- Equilibrium of temperature
- Equilibrium in the chemical reaction.
- Equilibrium with the surrounding factors like pressure.

Assuming all subjects have the same/equal credits, A is equivalent to 4, C is 2.
So, (4+4+2) / 3
n = (4+4+2) / 3
n = 10 / 3
n = 3.333333
n = 3.33
Hope this helps. :)
I'm not sure which barriers??.
The piece of evidence which President Reagan use to logically conclude that the astronauts were aware of the dangers was the previous accident on the ground
- Former President Ronald Reagan gave a powerful speech concerning the Space Shuttle Challenger disaster which claimed the life of all crew members including a teacher.
- The shuttle’s launch was said to have been delayed at least two times before the lunch date and due to pressure from the White House, it launch on January 28, 1986.
- Due to this previous issues that happened on the ground not space, the shuttle malfunction and burst to flames and if this issues were handled before takeoff, this incident would not have happened.
