Yes it is low in silica
Mount St Helens produces mostly dacite lava, which is relatively high in silica.
Because Mount Rainier is a Strato Volcano it has both quiet and explosive eruptions. Explosive(pyroclastic) flows have a high silica level. Quiet have low silica levels. The more silica the thicker the magma.
Mount Hood has high silica levels so the lava is felsic (Mt. Hood's silica values are as high as 64%).
High silica magma is more viscous (sticky) than low silica magma, so low silica magma lows easier.

Lava with high silica content will erupt explosively, if it has low silica content it will flow.
Shield volcanoes produce low-silica lava.
Kilauea erupts low-silica lava.
Salt does not contain silica.
no it has a generally low amount of silica.
The type of magma that is produced by Mount Bromo is felsic. In addition, it has high levels of silica and low levels of mafic magma.
No. Kilauea erupts low-silica lava.
