B-Al is different from the other pairs because it consists of elements from different groups in the periodic table. Li-Mg, Na-K, and Ca-Mg are pairs of elements from the same group which exhibit similar chemical characteristics.
i think its 2NaOH + Cl2 ------------> NaClO + NaCl + H2O i think
The symbols for these elements are: Sodium: Na Potassium: K Calcium: Ca Magnesium: Mg Chloride: Cl Bicarbonate: HCO3 Phosphate: PO4
Na+ + OH- + H+ + Cl- H2O + Na+ + Cl-
From greatest to least tendency to accept an electron, they are F, O, C, Li, and Be.
H2O (water) is a compound molecule. Ca, Na, Mg are elemental metals. NB When writing elemental symbols;- Single letter symbols are always a CAPITAL letter e.g. 'O' oxygen. Double letter symbols are always written as , first letter is a capital letter and the second letter is lower/small case. e.g. 'Ca'( Calcium). Na(Sodium) , & Mg (Magnesium). NOT as given with all capital letters.
Hard Water (I think I'm not sure it's just a guess)
H2O, Na, Ca, Cu, Fe and K.
H2O, Na, Ca, Cu, Fe and K.
H2O, Na, Ca, Cu, Fe and K.
H2O, Na, Ca, Cu, Fe and K.

Chlorides salts of Na, Mg, Ca.
Examples are Na+, K+, Mg+, Ca+, Cl-.
Reactions are:2 Na + Cl2 = 2 NaClNaOH + HCl = NaCl + H2O
