1When an element burns it joins up with oxygen to make a new compound called an oxideA group of students put 3.2 grams of the element aluminium into a crucibleAfter burning the aliminium had turned into a white powder which weighed 5.4 gramsa) Why Does The Aluminium Weigh More After Burning Than Beforeb) Suggest The Chemical Name Of The White Powder2What Are The Tests For The Following Gases?a) Oxygenb) Carbon Dioxidec) Nitrogen3Air Contains Oxygen, Nitrogen, Carbon Dioxide and Argon:a) Put The Gases In Order, The Most Plentiful FirstIf you know at least one answer, please tell me itThanks!
Most are aluminum, Ammonia, such as in dog urine, will corrode them.
Generally yes, unless you mean the housing or cover, that is usually steel or plastic.
The condenser outside is made of aluminumNo big scrap value!
1a) The aluminium reacts with the oxygen in the air b) Aluminium oxide 2a)light a wooden splint and then blow it out once only a red glow remains put it in the reaction test tube if oxygen is present, it will light again b) bubble through limewater turns cloudy if present c) not sure 3a) nitrogen, oxygen, argon, carbon dioxide (i think this is right hmm)
