A scients produces zinc iodide (Zn).
This is the method used
1. Viegh 0.500g of iodine
2 Dissolve the iodine in ethanol
3. Add an excess of zinc
4 Sir the mature until there is no further change
5. Fiter of the excess zinc
5. Evaporate of the ethanol
a Calculate the minimum mass of zinc that needs to be added to 0.500 g of iodine so
that the iodine fully reacts
The equation for the reaction is
Zn + Zniz
Relative atomic masses (Me): Zn = 65
1 = 127
