What is the name of the visible surface of the sun? (and surface doesn’t imply solid, as this surface’s density is 6000 times lower than the density of air)

a. photosphere

b. chromosphere

c. corona

d. core

e. radiative zone

The correct option is: a. Photosphere

Explanation:

Sun is the brightest star in the sky of our planet Earth and the principle component of the Solar System. It is a gaseous object that is made up of hot plasma and contributes 99.86% to the total mass of our Solar System.

The Sun does not have a clearly defined surface. The visible surface of the Sun is known as the Photosphere, which is the deepest visible portion of the Sun.

can i get the brainiest answer

i answered it first

n2(g) + 3h2-> 2nh3(g)   this is the balanced equation

note the mole ratio between n2, h2 and nh3.   it is 1 : 3 : 2   this will be important.

moles n2 present = 28.0 g n2 x 1 mole n2/28 g = 1 mole n2 present

moles h2 present = 25.0 g h2 x 1 mole h2/2 g = 12.5 moles h2 present

based on mole ratio, n2 is limiting in this situation because there is more than enough h2 but not enough n2.

moles nh3 that can be produced = 1 mole n2 x 2 moles nh3/mole n2 = 2 moles nh3 can be produced

grams of nh3 that can be produced = 2 moles nh3 x 17 g/mole = 34 grams of nh3 can be produced

note:   the key to this problem is recognizing that n2 is limiting, and therefore limits how much nh3 can be produced.
