Is magnesium explosive?
magnesium is highly flammable, so magnesium is explosive
Magnesium is highly explosive, electricity is created through heat (either that or electricity creates heat, can't remember which). While a trail of magnesium could conduct the electricity rather quickly, it can only be used once, because the heat enflames the magnesium. Also, as of yet, we are unable to capture the energy through such a method.
Explain why rhyolitic and andesitic magmas are associated with more explosive eruptions whereas basaltic magma is associated with less explosive eruptions?
Yes, but I would be careful. It could destroy the pump if made of certain materials. If it's a lead pipe or a nonmetal, you're probably fine, and yes, it will remove manganese and magnesium, although the reaction could be dangerous/explosive if proper care is not taken to make sure it works correctly.
