Trapped gas within the sun is known as

-

None of these are correct

Explanation: -

Solar prominiences are the trapped gases within the sun.

It extends outward into the sun's corona.

They consist of plasma cooler than that in corona.

They last from a day to even several months.

They are caused as a result of magnetic forces.

Solar prominences can extend over thousands of kilometers. Prominences vary considerably in size, shape, and motion.

They are of two main types, active and quiescent.

you didnt put any of the following

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
