Web8 sep. 2024 · Equilibrium is a pretty easy topic – big name, but easy idea. First, when you have a system made up of a bunch of molecules, those molecules sometimes combine. That’s the idea of a chemical reaction. Second, a chemical reaction sometimes starts at one point and moves to another. How do you write chemical equations? WebK sp = [Zn 2+] 3 [AsO 43 ¯] 2. Note how the mercury (I) ion is written. Hg 22+ is correct. Do not write it as 2Hg +. Writing [Hg +] 2 in the K sp expression is wrong. Here are ten chemical formulas. Write the chemical equation showing how the substance dissociates and write the K sp expression. 1) AlPO 4. 2) BaSO 4.

"WebEquilibrium constants (Keq) are a way of the quotient of a reaction which has reached equilibrium. The equilibrium expression allows a calculation to be performed which tells us the levels of reactants vs. products. A large Keq means that the reaction REALLY favors the formation of products (forward reaction). " - How do you write equilibrium expressions
