We are given with
4.35 g Phosphoric acid
5.25 g KOH
3.15 g K3PO4 produced
The reaction is
H3PO4 + 3KOH => K3PO4 + 3H2O
First, convert masses into moles.
Then, determine the limiting reactant.
Next, determine the maximum amount of K3PO4 that can be produced from the limiting reactant.
Lastly, calculate the percent yield by dividing the actual amount produced by the theoretical amount produced.

The chromosphere is the third and the lowermost layer of the sun and appears bright red. This chromosphere region is visible only during the total solar eclipse. Thus, option B is correct.
<h3>What is a solar eclipse?</h3>
A total solar eclipse is an event in which the new moon is in between the Earth and the Sun resulting in the formation of the dark shadow on the Earth's surface.
During this eclipse, the chromosphere region of the sun is visible as it was hidden by the photosphere before the eclipse. It shines bright red and yellow as the spectral line of the hydrogen alpha is emitted.
Therefore, option B. the chromosphere region is visible only during the total solar eclipse.

Mass is an intensive physical property because it is dependent on the size of the sample.
Molar mass FeSO₄ =151.908 g/mol
Volume = 450 mL / 1000 = 0.45 L
1 mol ----------- 151.908 g
n mol ----------- 0.8 g
n = 0.8 * 1 / 151.908
n = 0.00526 moles
M = n / V
M = 0.00526 / 0.45
M = 0.01168 mol/L⁻¹
hope this helps!
