Thanks

② solid zinc before the reaction is an element. protons = 30 , Electrons = 30 Charge = (Neutral). b. After the reaction, zinc is an im. (zn) protons - 30 , Electrons = 28 charge = -2 c. zinc is oxidised, (zn - zn 2+) .. Hydrogen before the reaction is an element, protons = 1, Electrom= 2. charge=0 (Neutral). b. After the reaction, hydrogen is an im (H+). protons - 1, Electron o charge = = = < Hydrogen is oxidised. (H -> H+) 6. Before reaction chlorine is protons = 17, electrom= 17 an element. , charge - Neutral b. In the reaction chlorine is reduced (elel) a. Zinc Chloride (anela) is an ionic b. Two ions are >zut? and er compound.
