No it would not. Al2O3 is very stable, and will not decompose
Cupric nitrate is initially blue when in its hydrated form. When heated, it will decompose to form copper oxide, turning black in color.
If you are refering to a mixture of aluminium chloride and aluminium, you can possibly heat up the mixture. Aluminium chloride will sublime (solid to gas) at about 180 degress celcius and the solid that remains would be aluminium.
To covalently bond aluminum and sulfur, you would need to have aluminum sulfide (Al2S3) formed through a chemical reaction. This can be achieved by heating a mixture of aluminum powder and sulfur in a controlled environment to allow the formation of covalent bonds between aluminum and sulfur atoms.
Francium would combine with water more readily than cesium. Francium is the most reactive alkali metal due to its position in the periodic table, so it would react more violently with water compared to cesium.
I'm not a chemist, but I rather feel that you'd only be able to combine the Al and the Si. But on a little research, indeed a few of the silicides exist, including a Mg variant, which when mixed with HCl, produces a gas Silane, SiH4, the Si analog of Methane. But more reactive. Given that He is a noble gas, it may not combine.
Aluminum oxide will not decompose readily upon heating because it is a very stable oxide. Aluminum oxide is passive and is less affected by environmental factors.
There are some waste products that take a very long time to decompose in a landfill. Thus, they should be recycled, instead of simply thrown away. For example, an aluminum can takes around 100 years to decompose.
It would be, if it were covalent. However, due to the large difference in electronegativity, any compound of aluminum and fluorine would be ionic. This compound would then be called aluminum IV fluoride. Aluminum does not readily form a 4+ ion, but rather forms a 3+ ion, so the correct formula for aluminum fluoride is AlF3.
Aluminum is not generally galvanized as the zinc would not be readily sacrificial for aluminum. There are steel products which derive rust resistance from a coating of aluminum and zinc alloy. Properly maintained, they will be rust free for 20 years or longer.
No, you idiot. Fruit is not recyclable, although it is compo stable while aluminum is recycled. if you tried putting fruit with aluminum recycling, it would just get in the way and be thrown out. If you put aluminum with compost, it would not decompose. You are a disgrace to the human race with your stupidity and just listen to your friends. This way, you wont hurt yourself by lets say running into walls or something
If the sugar is heated to a sufficient temperature, it will decompose and produce CO2 (carbon dioxide) and H2O (water). This would be considered a combustion reaction.
If you are talking about aluminum foil, it takes a very long time. Aluminum is already in its elemental form, so there is no 'compound' to break down. Aluminum does not rust or corrode under normal exposure to the environment. The small amount that oxides on on its surface act as an inhibitor to further oxidation. So, an aluminum foil that is buried in a dump would last longer than our lifetimes.

It would decompose
It depends on how much heat is added; for instance: Chemical change indicates a change in the chemical formula. Heating it would eventually decompose it, so it is a chemical change if you are decomposing it. A change in phase (solid-->gas) would be a physical change, so as long as the chemical formula stays the same, meaning it doesn't react with anything in the air or decompose, it would be a physical change
