Answer:
Explanation:
Aluminium is used in rechargeable battery.
Aluminium ions provide the energy by flowing from anode to the cathode.
When the battery is recharged these ions comes to the anode.
The one ion gives three electrons. Which means one Al⁺³ is equal to the three Li⁺ ions. So, three unit of charge giving by ions increase the energy storage capacity.
The rechargeable batteries with aluminium gives low cost and low flammability.
It is safe to use because of inertness of aluminium and also easy to use in ambient environment.
Aluminium also have high volume capacity than lithium which means energy storage per volume is greater.
Its charge discharge cycles are also greater.
The aluminum ion batteries are also smaller in size.

Explanation:
Answer:
4.78 %.
Explanation:
<em>mass percent is the ratio of the mass of the solute to the mass of the solution multiplied by 100.</em>
<em></em>
<em>mass % = (mass of solute/mass of solution) x 100.</em>
<em></em>
mass of MgSO₄ = 50.0 g,
mass of water = d.V = (0.997 g/mL)(1000.0 mL) = 997.0 g.
mass of the solution = mass of water + mass of MgSO₄ = 997.0 g + 50.0 g = 1047.0 g.
<em>∴ mass % = (mass of solute/mass of solution) x 100</em> = (50.0 g/1047.0 g) x 100 = <em>4.776 % ≅ 4.78 %.</em>
They both build up to form electricity
