At high temperatures, sulfur combines with iron to form brown-black iron(II) sulfide:
taurus [48]

The percent yield : 79.9%

<h3>Further eplanation </h3>

Percent yield is the comparison of the amount of product obtained from a reaction with the amount you calculated

General formula:

Percent yield = (Actual yield / theoretical yield )x 100%

An actual yield is the amount of product actually produced by the reaction. A theoretical yield is the amount of product that you calculate from the reaction equation according to the product and reactant coefficients

Reaction

Fe(s)+S(s)⇒FeS(s)

The reaction produces 6.29 g of iron(II) sulfide⇒an actual yield

The maximum  amount that can be produced is 7.87 g ⇒ A theoretical yield

\tt \%yield=\dfrac{actual}{theoretical}\times 100\%\\\\\%yield=\dfrac{6.29}{7.87}\times 100\5=79.9\%

The Iris is located at the back of the cornea.The quantity of light that falls on the eye is determined by the Iris. The Iris is colored.

Lens allows light to be focused on the retina. It is behind the Iris.

The retina is the part of the eye that senses light. The retina sends the light signal it senses to the brain for interpretation. It is the innermost if all the options given.
