Answer:
A viscous magma containing 52% silica and gas would produce a felsic, or explosive, eruption. Felsic eruptions typically produce lava flows that are thick and sticky, and can contain a high concentration of silica. These eruptions can also produce large ash clouds and pyroclastic flows, as the gas trapped in the magma expands and escapes during the eruption. Examples of felsic volcanic eruptions include the eruption of Mount St. Helens in 1980 and the eruption of Mount Pinatubo in 1991.
