Location the element zinc (Zn) on the periodic table:
Group number : 12
Period number : 4
Block : d block
Element : Transition elements.
Part 2:
Protons in an atom of Zn: 30
Part 3:
Electrons in a Zn atom: 30
Part 4 :
Neutron in an atom of Zn: 35
The equation is :
moles=mass/molar mass
so, the mass is 203 and molar mass is 159.69
You divide the 203 by 156.69 as the equation shows
so the moles is 1.27 mol.
A solid formed from liquid reactants chemical reactions is called a precipitate.
