believed that carbonic acid could not exist as a pure compound. However, in 1991 it was reported that NASA scientists had succeeded in making solid H₂CO₃ samples. Carbonic acid is a weak acid that forms when carbon dioxide is dissolved in water. The chemical equilibrium equation ...
What Is Dynamic Equilibrium? Chemical reactions can either go in both directions (forward and reverse) or only in one direction.The ones that go in two directions are known as reversible reactions,and you can identify them by the arrows going in two directions, like the example below. ...
spontaneous reaction. In the chemical equilibrium between ATP and ADP in an aqueous solution, ATP is eventually almost completely converted into ADP. Before reaching equilibrium, the Gibbs free energy change of the system is negative, indicating that the system can perform non-volume work on the ...
The interesting part about thermal equilibrium is that we want to avoid it when it comes to insulating buildings. That's why we install insulation materials, so that our house doesn't become hot in the summer and cold in the winter. This is probably one of the few equilibrium that we don...
