The powder burns much faster than the ribbon, providing a quick bright flash. The ribbon would burn more slowly, providing a longer lasting light but not as bright.
See the Related Question for why a powdered substance will generally react faster.
A reaction occurs more quickly when powdered iron is used instead of a single piece of iron of the same mass because the powdered iron has a much greater surface area and all chemical reactions take place on surfaces.
No. Instead, the magnesium ribbon is dissolved and metallic copper precipitates.
Mg(NO3)2 {note correct case for "O"} is not an element at all. Instead it is a compound of three elements, magnesium, nitrogen, and oxygen.
Zinc and magnesium are too reactive.
magnesium is neather a metal nor a non metal. instead it was discovered on the moon in 1899 on the first space walk. since then it has been used to build flame resistant bridges and the 2010 aero sun probe.
It forms magnesium oxide. :)

It was an early (1860-1880) type of wet plate photography that had an advantage of requiring only a very short exposure time, instead of the three to five minutes most photographic processes required at the time.

A radio that gets power from batteries instead of the outlet on the wall.
No; it prodces hydrogen gas instead: Magnesium is far above hydrogen in the electromotive series.
