Answer:
0.396 grams of lithium
Explanation:
Lithium-ion batteries have the main feature of using lithium salts as a "bridge" between the positive pole (anode) to the negative (cathode) to allow the passage of energy that will give life to our device. In the case of lithium polymer batteries, the difference is that the lithium salt is contained in a polymer, or gel, to keep it safe from spills.
In both cases, when the battery is discharging, lithium ions travel from the cathode to the anode through their "bridges" to supply the energy until all the ions are in the anode, it is at this time when the battery is out of stock The ions travel in the opposite direction during charging (from the anode to the cathode).
<u>The calculation used to determine the amount of lithium that the lithium cell batteries have is as follows</u>:
0.3 x amp hour capacity = g of lithium
where amp hour = Ah
<u>In our case</u>:
0.3 x 1.32 = 0.396 g of lithium
Answer:
The synthesis of aspirin is known in organic chemistry as an esterification reaction. This is a substitution reaction in which an alcohol (the –OH group in salicylic acid) reacts with acetic anhydride to form an ester, aspirin.
Explanation:
Answer:
1. Ionic solids dissolve in water.
2. Ionic solid is a better conductor compared to covalent solid.
Explanation:
1. Ionic solids dissolves in water because the water molecules hydrate the ions.When ionic compounds dissolve in water, they break apart into the ions that make them up through a process called dissociation.
Whereas covalent solids don't dissolve in water, instead making a separate layer on the water's surface.
For example table salt that is NaCl is an ionic solid.When we add the salt in water it completely dissolves in water and disappears on the other hand oil is a covalent solid, when we add it in water it does not dissolve and forms a layer on water surface.
2.Ionic solids conducts electricity when it dissolves in water. Because in aqueous form there are ions which conducts electricity.
But covalent solids does not conduct in any form neither in pure form nor in aqueous form because they are bond with shared electrons having no ions which conducts electricity.
Answer:
Usually the Bohr model, sometimes the rutherford model
