The difference between sunspots solar flares and prominence

Sunspots are dark areas on the surface of the Sun that are cooler than surrounding areas. They appear in groups, vary in size, and cycle in number over an 11-year period. Solar flares are sudden eruptions of energy from a small area of the Sun's surface. They are extremely hot (10 to 20 million degrees Celsius) and extend into the corona. Solar flares occur near sunspots and can disturb radio communications on Earth.

Sample response on E2021

1. for the first question, we must find the mass of the anhydrous salt, mgso₄. the molar mass for mgso₄·7h₂o is 246.47 g/mol, while that of mgso₄ is 120.37 g/mol.7.834 g mgso₄·7h₂o * 1 mol mgso₄·7h₂o/246.47 g * 1 mol mgso₄/1 mol mgso₄·7h₂o * 20.37 g mgso₄/mol = 0.647 g mgso₄

2. mass of water = mass of sample - mass of anhydrous salemass of water = 7.834 - 0.647 = 7.19 gpercent water in hydrate = 7.19/7.834 * 100 = 91.74%
