Answer: well liquids can Adapt to any form or shape , but if it’s a definitive (volume) Then it would be a solid
Explanation:
Solid both takes up the shape of the object , while filling its volume up as well

Answer:
See Explanation
Explanation:
In electrolysis, a solution called the electrolyte is decomposed by the passage of direct current through it.
The points through which current enters and leaves the electrolyte are called electrodes. In electrolysis, oxidation occurs at the anode and reduction occurs at the cathode.
In the electrolysis of water; at the anode oxygen is produced as follows;
4OH^-(aq) -----> 2H2O(l) + O2(g) + 4e
The mass for of aluminum that is produced by the decomposition of 5.0 Kg Al2O3 is 2647 g or 2.647 Kg
calculation
Write the equation for decomposition of Al2O3
Al2O3 = 2Al + 3 O2
find the moles of Al2O3 = mass/molar mass
convert 5 Kg to g = 5 x1000 = 5000 grams
molar mass of Al2O3 = 27 x2 + 16 x3 = 102 g/mol
moles =5000 g/ 102 g/mol = 49.0196 moles
by use of mole ratio between Al2O3 to Al which is 1:2 the moles of Al = 49.0196 x2 =98.0392 moles
mass of Al = moles x molar mass
= 98.0392 moles x 27g/mol = 2647 grams or 2647/1000 = 2.647 Kg
