For the chemical reactiom to be at equilibrium:
1- The rate of forward reaction must be equal to the rate of the reverse reaction.
2- The mass of EACH element must be equal before and after the reaction (no NET change in mass), otherwise the equilibrium will shift.
Important note: you need to check the mass of each element before and after the reaction (i.e, reactants side and products side) and the not the mass of the system as a whole. This is because the mass of the whole system will be preserved whether the system is at equilibrium or not (this is the fundamental law of mass conservation)
The PH of water is 7 because it contains an equal amount of h and oh- ions.
The recipe for an omelet are:
<u>Ingredients</u>
- 1 Egg
- Salt and pepper ( 1 tablespoon )
- Butter ( 1 tablespoon )
<u>Recipe:</u>
- Turn on the heat and place a pan on it.
- Add butter to the pan.
- Crack the egg and whisk it properly.
- Add the whisked omelet onto the pan and stir.
- Add salt and pepper.
<h3>How to illustrate the information?</h3>
When we turn on the heat and place the pan, a heat transfer takes place and heat transfers from one body to another.
When we add butter to the pan, then the temperature of the pan was more than that of the butter.
Since the melting point of butter was less than the temperature of the pan, the the melting of butter takes place.
When we add the egg, the evaporation of the liquid present in the egg yolk and the egg white takes place.
These are the chemical reactions depicted.
