Question

The text mentions the formation of iron (II) sulfide (FeS) in hard-boiled eggs due to a reaction between iron in the yolk and hydrogen sulfide gas (H_2S) from the egg white.

What is the word equation for this reaction?

A) Iron (II) sulfide + hydrogen sulfide gas → iron + hydrogen gas
B) Hard-boiled eggs + hydrogen sulfide gas → iron (II) sulfide + hydrogen gas
C) Iron + hydrogen gas → iron (II) sulfide + hydrogen sulfide gas
D) There is no word equation mentioned in the text.

Answer 1

The text does not specify a word equation for the reaction between iron and hydrogen sulfide to form iron (II) sulfide, but the correct inferred equation is: Iron + Hydrogen sulfide → Iron (II) sulfide + Hydrogen gas.

Step-by-step explanation:

The word equation for the reaction where iron in the yolk of a hard-boiled egg reacts with hydrogen sulfide gas from the egg white to form iron (II) sulfide is not explicitly given in the text. However, based on the provided information about the reactivity of iron and hydrogen sulfide, we can deduce the general form of the reaction. When iron (Fe) reacts with hydrogen sulfide (H2S), iron (II) sulfide (FeS) and hydrogen gas (H2) are produced. Therefore, a correct word equation for this reaction would be:

Iron + Hydrogen sulfide → Iron (II) sulfide + Hydrogen gas

Thus, the correct answer to the student's question would be that the text does not specify a word equation, but one can be inferred as shown above.
