Answer:
Li⁺
Explanation:
In ion formation, the ionization energy plays a very important role. To form an ion, an atom will lose or gain an electron to become charged.
The higher the ionization energy of an atom, the more the energy required to remove an electron from it to form an ion.
- Ionization energy is the energy required to remove an electron from an atom.
- It is the readiness of an atom to lose an electron. The lower the value, the easier it is for an atom to lose an electron and vice versa.
Generally, down the group, ionization energy decreases. Since both potassium and lithium are in group 1, Li will have a higher ionization energy. It will take more energy to form Li⁺ compared to K⁺.
In a chemical formula, the part to the left of the arrow represents the reactants. The reactants are all the chemical elements that will react with each others to make the products (which will be on the right part of the arrow).
Example:
H2 + O2 --> H2O
H2 and O2 are the reactants (on the left part of the arrow) and H2O is the product (on the right side of the arrow)
Hope this helps! :)
Answer:
Water is added to a concentrated solution of sodium thiosulfate to dilute it.
Explanation: Water is a universal solvent. It has the capability to dissolve many substances in it. When water is added to a solution, the concentrated solution can be diluted. Dilute solution means the presence of water in high amount and solute quantity is very low.
What are the choices? I'll answer once you tell me those
