Mass = mole x molar mass
Explanation:
The mole of the substance used in the bakanced eqn multipled by its molar mass equals to Its mass
A) Molar mass gold ( Au) = 196.96 g/mol
1 mole Au ----------- 196.96 g
? moles Au ---------- 35.12 g
35.12 x 1 / 196.96
= 0.178 moles of Au
_____________________________
b) 196.96 g --------------- 6.02x10²³ atoms
35.12 g ---------------- ( atoms ? )
35.12 x ( 6.02x10²³) / 196.96
2.114x10²⁵ / 196.96
= 1.07x10²³ atoms

I think the answer is Aluminium is oxidized from 0 to +3. A half reaction is a reduction or oxidation reaction component of a redox reaction. It is got by considering the change in oxidation states of independent substances involved in a redox reaction.
