<span>Nickel carbonate tetrahydrate</span>
Answer:
a or b
it is either a or be because it will get warmer but might be a little cloudy
This answer is D) none of these
Answer:
Sodium chloride, a white crystalline solid, contains a density of 2.165 g/mL, the melting point of 801 °C, and the boiling point is about 1,413 °C. It is also available as aqueous solutions with different concentrations, which are known as saline solutions.
A) Cl- ion
B) These energies are equal for all forms of the same element
Explanation:
The ionization energy for a chlorine atom is equal in magnitude to the electron affinity of Cl⁻ ion because these energies are equal for all forms of the same element.
- Electron affinity is the energy released in adding an electron to a neutral atom in the gas phase.
- Ionization energy is the amount of energy required for the removal of an electron in atom or ion.
- Here the energy released when an electron is added to the Cl atom(electron affinity) to form a chlorine ion is the same energy that would be required to remove the added electron from the ion to form an atom(electronegativity).
- Here we find out that both energies are the same for the atom of Cl that is gaining electron and for the ion in which electron is being removed.
