Zinc metal reacts with hydrochloric acid (HCI) according to the equation: Zn(s) + 2HCl(aq) - ZnCl(aq) + H2(g) Part A How many grams of hydrogen are produced if 300 g of zinc reacts? AEP O ? M . Submit Request Answer
how do these things affect eachother? if I have Zn(s)|Zn2+(aq)||Ag+(aq)|Ag(s) and the solution in the salt bridge is changes to CH3OH from potassium nitrate. if I have Fe3+(aq)|Fe2+(aq)||Ag+(aq)|Ag(s) and the iron (ii) nitrate solution is replaced with salt water if I have Cu(s)|Cu2+(aq)||MnO4^-(aq)|C(s) and I replaced the carbon electrode with silver the rest are voltaic cells if I have Co (s) | Co2+ (aq)|| Cu2+(aq) |Cu (s) instead of a porous cup we turn it into two half cells connected...
