<span>Answer:
K because it is metal and typically forms ionic bonds. Ar is also unlikely to form any bonds because it has a full outer shell of electrons, but it can form covalent bonds.</span>
I think the answer should be 2.19 J/g*K. The specific heat means the energy absorbed by 1 g substance to increase 1 Kelvin temperature. And keep the unit the same.
In the past a scientist named dalton produced an atomic theory. There were certain problems regarding his views. So, later on scientists like chadwick, rutherford and thompson added some fresh light for the real identification of the atom.
dalton said the atom was the smallest unit and it CANNOT BE DIVIDED ANY FURTHER.
NOTE... this was renected with the discovery of the proton, neutron and electron as the sub atomic particles.
Answer:
Ba^2+ = Barium ion [Cation]
Cl-= Chloride ion [Anion]
Explanation:
Ba(OH)2 + HCl = BaCl2 + H2O is the reaction that happens.
You make an ionic compound which is soiuble in water Barium Chloride. The cation is Ba^2+ = Barium ion, Cl^ - = Chloride ion
Postive ions are cations and negative ions are anions thus
Ba^2+ = Barium ion [Cation]
Cl-= Chloride ion [Anion]
