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.
A volcano that forms from lava containing relatively small amounts of gases and silica is typically a shield volcano. These volcanoes have broad, gently sloping sides and are primarily built up by the flow of low-viscosity basaltic lava, which can travel long distances. The low gas content allows for less explosive eruptions, resulting in relatively calm lava flows. Examples include Mauna Loa and Kilauea in Hawaii.
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)
In small amounts, yes. Magma contains some hydrogen from water that has been subducted into the mantle.
