Na+ and Cl- are spectator ions.
Zn(s) → Zn2+(aq) + 2e- and Fe3+(aq) + e- → Fe2+(aq)
Hydrochloric acid and sodium hydroxide yield salt and water H+ + Cl- + Na+ + OH- --> Na+ + Cl- + H2OComment:In solutions you better leave unchanged ions ( Cl- and Na+) out of the balanced equation: called to be 'tribune ions' (people on the tribune don't take part in the 'match'):H+ + OH- --> H2O This looks simpler than: H+ + Cl - + Na + + OH- --> Na + + Cl - + H2O
since the powers 3+ = 3- the cancel each other out so the formula becomes FeN hope this helped.
Calcium Chloride
The chemical equation is:3 AgNO3 + FeCl3 = 3 AgCl + Fe(NO3)33 Ag + 3 NO3- + Fe3+ + 3 Cl- = 3 AgCl(s) + 3 NO3- + Fe3+
Na+ and Cl- are spectator ions.
b. Fe3 plus ions
Ferric or Iron (III) = Fe3+Chloride = Cl-Fe3+ + Cl- = Fe2Cl
When 90.0mL of 0.10M Fe3 plus 3 is added to 10.0 mL of SCN minus 1, you get an equilibrium molar concentration of FeNCS plus 2. This is determined from a calibration curve of 1.0x10-6 mol/L.
Hg will have 80 electrons.
FeBr2 + H3PO4 <--> Fe3(PO4)2 + HBr
FeSO4 + K3PO4 ---> Fe3(PO4)2 + K2SO4
ferrous ions and Fe3+ is ferric ion
The answer is 3. Fe -> Fe3+ + 3e
No, it doesnot as Potassium has only one positive charge.
An example is the ferric ion: Fe(III) or Fe3+.
