Answer = 43.2
Because to find the mass you multiply the amount of moles ( 1.6) by the mass of the element ( mass of aluminium is 27) so
1.6 x 27 = 43.2g

Because the scale is much larger, and a larger pool can collect more energy than a small pool, and it is more likely that it would have more energy spread throughout it.
Hey there!
Your answer is c. by the transfer of one or more electrons from one atom to another.
Ions can be positive or negative. Positive ions are called cations, and negative ions are called anions.
Electrons are transferred because two atoms have a large difference of electronegativity and the electrons are shared so unequally that the electrons are completely transferred from one atom to another, forming ions.
Hope this helps!
Answer : There are many ways to use electric current, but as you have asked for only three, here are some of them along with the change in their energy transformations;
1) Using a light bulb which consumes electrical energy and the energy is transformed into light energy, making everything visible for us.
2) Using a power tool makes use of electrical energy and the energy is transformed into mechanical energy for multipurpose use of cutting woods.
3)
Using electrical iron converts electrical energy into thermal energy to heat the iron and enables the user to iron crease-free clothes.
