The answer is: first substance is base and second is acid.
Bases, for example solution of sodium hydroxide (NaOH) feels slipery.
Sodium hydroxide dissociation in water: NaOH(aq) → Na⁺(aq) + OH⁻(aq).
Ionic compounds are good good electricity and heat conductors, because ionic compounds have mobile ions (cations and anions) that are able to transfer electrical charge.
In second reaction, magnesium is oxidized from oxidation number 0 to +2 and hydrogen is reduced from +1 to 0 (hydrogen gas).
