It is 1-3-1-3
so 1Al2O3 + 3H2So4 ---> 1Al2(So4)3 + 3H2O
Answer:

Explanation:
We know we will need a balanced chemical equation with masses and molar masses, so, let's gather all the information in one place.
You don't tell us what the reaction is, but we can solve the problem so long as we balance the OH.
M_r: 58.32
Mg(OH)₂ + … ⟶ … + 2HOH
m/g: 58.3
(a) Moles of Mg(OH)₂

(b) Moles of H₂O
The molar ratio is 2 mol H₂O = 1 mol Mg(OH)₂.

The reaction will form
of water.
Answer: Location 3 is warmer than location 2 and 1
Explanation:
I'm pretty sure the answer would be that the metal is conductive, which travels through the copper wires.
