I can't answer all of them, but here's what I got: 1Aluminium is fairly heat resistant which makes it ideal for use in the oven and can be made into very thin, flexible sheets which can be formed to various shapes2Aluminium can be used to cover foods, either to store them or to heat them (see 1)3Aluminium, as mentioned above, is not a good conductor of heat4Not sure on this one5Fe 2 O 3 6Iron is strong and is a good heat conductor, but does not lose its strength when exposed to moderate amounts of heatAdditionally, iron (iii) oxide has good magnetic properties7Iron can be found in commonly in cookwareIron (iii) oxide is often used in magnetic storage, for example in the magnetic layer of floppy disks8Iron conducts heat fairly well, and is thus often made into pots or pans for use on the stove top, and also acts as a magnet 9Iron rusts if left out in the elements, so kitchenware should not be allowed to soak for too long in the sinkAdditionally, iron is definitely not a non-sticking surface, so food needs to be cooked in some type of oil or other slick material 10Magnesium burns at a fairly low temperature (I forget the exact number), and flares bright white when burning, which makes it visible from a very long distanceAdditionally, other elements may be added to give color to the burst of flame.
