history WWI?

The Battle of Vimy Ridge is the obvious choice, and probably the easiest.

Sorry for posting in the incorrect section, yet... this is concerning your question "what's the chart that is made to describe a chemical equation?". thank you for the ten factors btw. I observed which you extra a be conscious asserting there grew to become right into a delta on the left of the chart. The proscribing/extra chart is used for apprx. finished reactions ("-->"). there is yet another chart it somewhat is used for incomplete reactions ("<==>"), and that's the only with the delta on the left. Does Le Chatelier & chemical equilibrium sound commonplace? The format is: chemical equation (balanced; e.g. a + 3b <==> 2c + d) preliminary concentrations (frequently in moles/litre) exchange in concentration (DELTA concentration; oftentimes + or - x) equilibrium concentrations (preliminary + exchange in concentration) ok = equilibrium consistent [ ] = concentration Then ok = [c]^2[d] / [a][b]^3 (following above occasion equation). the fee of ok is frequently used to discover concentration of one of the compounds so pH (-log[acidic ion]) or pOH (-log[easy ion]) might nicely be calculated. And pK_w = pH + pOH = 14.00.
