Atoms will be split into hydrogen and oxygen. A deep blue solution will be formed. Light will be given off. It will create a small explosion.
please mark me as brainlest , thanks!
First this is not Chemistry..
And to answer this you need to know simple formula :)
Wattage = Voltage * Ampere
So the answer is 480 Wattage
Assuming there is excess acid, the equation for the reaction is Zn + 2HCl -> ZnCl2 + H2.
Mols of zinc = 20/65 (mass/relative atomic mass)
Ratio of Zn : ZnCl2 = 1 : 1
Hence mols of Zinc = mols of Zinc chloride
Mass of ZnCl2 = (20/65)(65+71)
= 41.8g
