B because : it gives off carbon dioxide (the gas) it gives off water (the water(lol)) it also gives off a salt. 2. C because : aluminum forms with oxygen to form an amphoteric solution, sodium forms a basic solution with water and so does zine. Through the process of elimination, sulphur is the only one that would fit this category. 3. C because : carbon would form to create either carbon dioxide (acidic oxide) or carbon monoxide ( neutral oxide) sulphur would form sulphur dioxide (acidic oxide) hydrogen would form water when reacted with oxygen and i dont think its possible for hydrogen and oxygen to form hydroxide by themselves...so that leaves good ol' C magnesium is able to be gaseous and nonetheless if burned in air it would combine with oxygen to form a basic oxide which would dissolve in water to form an alkaline solution. -- and its the only one which would have a pH greater than seven ANYWAY. --Gr 11. Too bad it took me this long to find this awesome page... I have my Christmas final in Chemistry tomorrow and this was a good way to review. --AshantiWasHere :D 1. B because :

My answer to ques. 2 is Sulphur oxide cuz its an acidic oxide and Ques. 3 is magnesium because it forms a basic oxide and when dissolved in water it will form an alkaline solution having a ph more than 7 gr8 site, really helped me out:D

what do you mean by that?
