Answer:
24.3049 amu
Explanation:
Atomic mass of magnesium = percentage average of its isotopes
= 23.9850 x .7899 + 24.9858 x 0.10 + 25.9826 x .1101
= 24.3049 amu
Answer:
B. Prominences are composed of cool, dense gas.
C. Prominences can disturb radio communications on Earth.
D. Prominences cycle over an 11-year period.
E. Prominences are loop shaped.
Explanation:
Prominence is the release of high energy particles or dense gases in the form of a loop shape from the surface of the sun. It is cooler and flows out into the Sun's hot atmosphere known as corona.
Once formed, prominence can be quiescent in the space for some period of time before it erupt and get ejected. This eruption and ejection can lead to coronal mass ejections which extends over a very long distance.
When compared to the Sun's temperature, prominences are cooler.
