Consider the following unbalanced reaction. P4(s) + F2(g) PF3(g) How many grams of F2 are needed to produce 212 g of PF3 if the reaction has a 79.8% yield? I did 212/.798=265.66 grams do I convert that to moles next?

I'm supposed to balance a redox reaction that occurs in an acidic solution. I already balanced it(h**p://, but how do I tell if a half-reaction is oxidation or reduction? I know an oxidation reaction loses electrons, and an ...

the solubility of AgCl in HCl is a. low, as Cl- ions cause an equilibrium shift towards the solid form b. low, as Ag+ has already reacted with Cl- c. high, as HCl readily ionizes d. high, as AgCl can then form e. high, as H2 forms, then escapes (a) The scant amount of Ag+ is ...
