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.
Lord Kelvin, were he alive today, would be considered a Thermochemist. Thermochemistry is interested in the role of heat in chemical reactions. This includes the role of heat both as a biproduct of chemical reactions and a facilitator.
Kelvin's description of absolute zero is an important concept in thermochemistry. At absolute zero, there is no movement of molecules, and no energy available facilitate chemical reactions.
Answer:
The structures are attached in file.
Hydrogen bonding and intermolecular forces is the reason for ranks allotted.
Explanation:
In determining Lewis structure, we calculate the overall number of valence electrons available for bonding. Making carbon (the least electronegative atom) the central atom in the structure, we allocate valence electrons until each atom has achieved stability.
In order of decreasing affinity to water molecules:
This is due to the fact that the 
will accept protons more readily than the bicarbonate ion, 
. Carbonic acid, 
will not accept any more protons, hence it is the least attractive to water molecule, even though soluble.
Answer: i think the best bet i can give you is Option C (2:3)
Explanation: i apologize i haven't done chem in 2 years
but however to put it in retrospect the finished equation is 2(AL)^+3 3(O)^-2
