"n" represents principal energy level or principal quantum number. Principal energy levels are then subdivided into sublevels. The level of principal energy level is always equal to number of sublevels. Therefore if <span>principal energy level</span> = 4, then there are also 4 sublevels present, namely: 4s, 4p, 4d and 4f sublevels.
Im pretty sure the right answer would be 150, but correct me if im wrong please!

Answer:
Option A, light energy from the sun
Explanation:
In the process of photosynthesis, the energy from sun in the form of light and heat is taken to undergo glycolysis and prepare glucose/starch (chemical).
Thus, the light and heat energy of sun is converted into the chemical energy.
Option B and C are incorrect because no kinetic energy or chemical energy is taken from any source.
Option D is also incorrect because heat is taken but it is not taken from the surrounding environment. The source of heat energy is sun.
Thus, only option A is correct
If x is H+ then <span>x/0.15 = 0.03 and x = 0.0045 M </span><span>and
</span>
<span>Ka = x^2/(0.15 - x) = 0.0045^2/(0.15 - 0.0045) = 1.39 x 10^-4</span>
