The reason for an opals characteristic flash is because the sphere of silica are mixed with a small amount of what ? A.) Magma B.) Hydrogen C.) Methane D.) Water

Silica content influences magma behavior-magmas have high silica content, are viscous (thick), and erupt at a lower temperature-magmas have much lower silica content, more fluidlike behavior, and erupt at a higher temperature

Explanation:

8

explanation:

each principal energy level above the first contains one s orbital and three p orbitals. a set of three p orbitals, called the p sublevel, can hold a maximum of six electrons. therefore, the second level can contain a maximum of eight electrons - that is, two in the s orbital and 6 in the three p orbitals.

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.
