Video transcript

Everyone. So I asked us 3.5 moles of calcium bromine And one more solution of sodium bromine. I asked, taking the temple the r minus ions. It's gonna be no, cannot determine which one has more p. R minus ions since there's no volume given, since we're giving the majority of sodium bromide. But we need the volume of the solution to find the mall of ions. It's the most part the volume of the solution by the polarity to cancel the volume and find the mold of the ions. Then we can multiply this number by how many atoms of romaine have in the compound. Thanks for watching my video and I hope it was up for.

The metal cadmium tends to form Cd2+ ions. The following observations are made: (i) When a strip of zinc metal is placed in CdCl2(aq), cadmium metal is deposited on the strip. (ii) When a strip of cadmium metal is placed in Ni(NO3)(aq), nickel metal is deposited on the strip. (b) Which elements more closely define the position of cadmium in the activity series?
