D. Volcanoes that have large amounts of silica
This would result in a non-explosive, "runny" eruption, similar to what you get in Hawaii, where the volcano simply pours out lava. Explosive reactions occur when rocks contain large amounts of water and silica, which flash into steam, resulting in a rapid expansion, and thus a dangerously explosive reaction.
The main element in steel is usually iron. It also contains small amounts of other substances, to improve its properties. Often it contains some carbon (not a metal), and sometimes smaller amounts of other metals.
Sand (silica) - Most of the material make-up Limestone Soda Ash Small amounts of aluminum containing materials (Felspar)
No more than anything else. Almost all matter you encounter will contain small amounts of radioactive elements or isotopes. Granitic magma can contain small amounts of uranium, but not enough to pose any immediate danger. However, areas built on granitic bedrock can face a potential danger from radon.
In small amounts, yes. Magma contains some hydrogen from water that has been subducted into the mantle.
