Question

What are the formulas for these combos:
Lead (III) nitrate and potassium iodide
Magnesium metal and hydrochloric acid

And also Electrolysis of water?

Answer 1

I got: Pb(NO3)2 + 2 KI
Mg + 2 HCl = MgCl2 + H2
2 H2O

Answer 2

correct...
electrolysis of water will give you
H20 =(reversible) H+ + OH-
then,
at cathode 2H+ + 2e- = H2
at anode 4OH- = 2H2O + 02 + 4e-

Answer 3

Thank you.

Answer 4

sure ^^
