Answer:
Aqueous sodium ions, Aqueous chloride ions
Explanation:
Sodium chloride dissociates into Na+ and Cl- ions in water
Sodium chloride crystals may also be present in case of saturated solution
Answer:
in the excited state
Explanation:
Because in excited state an atom has more energy
Answer:
violet has a frequency of 668-789 THz :)
Explanation:
Answer:
B
Explanation:
First of all it is important to know that a half filled orbital is particularly stable. In phosphorus all the electrons occur singly in the 3p sublevel minimizing inter electronic repulsion hence it is more difficult to remove an electron from this energetically stable arrangement. In sulphur, electrons are paired in one of the 3p orbitals thereby lowering the energy of that level due to instability caused by interelectronic repulsion between two electrons in the same orbital.
Answer:
Neutralization reaction is a reaction between an acid and a base. In general, when the reaction is performed in aqueous media, produce water and salt.
Explanation:
Arrhenius defined a base as a substance who forms OH- ions. Bronsted, define it as an proton acceptor.
On the other hand Arrhenius defined an acid as a substance who form H+ ions. Breonsted define it as proton donor.
Acid + base ----> salt + water
A salt is an ionic compund formed by a cation and anion. All salts are strong electrolytes. An example of a neutralization reaction is:
HCl (ac) + NaOH (ac) -------> NaCl (ac) + H2O(l)
Nevertheless, because the acid and the base are strong electrolytes, in water they are completely dissolved actually look like this:
H+ (ac) + Cl(ac) + Na+(ac) + OH-(ac) ------> Na+(ac) + Cl-(ac) + H2O(l)
