jayasica: sis plz explain me also
anisha1764: hey...Mg has valency 2 while chlorine has 1 so you also know that valency exchanges when writing a chemical formula so..the valency 1 of cl goes to Mg and valency 2 of Mg goes to cl and hence it changes into Mgcl2
jayasica: thanks
anisha1764: similarly you can get the chemical formula of rest....do it...it is easy..
anisha1764: so u understand or not
