    metal oxide + water always results to hydroxide. Since MgO is a metal oxide, MgO + H20 -> MG(OH)2 does that make sense?

    that's supposed to be Mg(OH)2

    wait, I think I got it. you said: metal oxide + water always results to hydroxide so you placed (OH)2 after Mg is it always metal oxide + (OH)2? I mean you will "always" just stick (OH)2 after the metal oxide if the reaction is metal oxide + water?

    not always stick (OH)2 it has 2 because the charge of Mg is 2+. So by the "criss-cross" method you get (OH)2 make sense?

    you just stick OH after the metal oxide then apply the necessary subscripts

    Cu + Pb(NO3)2 does not react. However *if* it does then it will just be a single displacement reaction Cu + Pb(NO3)2 --> Cu (NO3)2 + Pb

    I think "KClO3 + O2" should be KClO3 + MnO2 because it is stated that "place a mixture of KClO3 and MnO2 in a test tube." then I heated it
