How many grams of iron (3)sulfide are produced when 131 grams of iron react with excess sulfur?
Tomtit [17]

<u>We want the molar mass (gfm) of Fe and FeS.</u>

Fe = 55.8 g/mol and FeS = 87.8 g/mol (55.8 +32.0).

<u>Explanation:</u>  

We want  ratio between Fe:FeS 8:8. This comes from the coefficients of the equal chemical equation.

Now we set up conversion factors following the roadmap from above.

Unit we want in the numerator, unit to cancel in the denominator.

Multiply the numerators, and divide the denominators.

(131.0)gFe \times 1molFe/(55.8)gFe \times 8molFeS/8molFe \times 87.8gFes/1molFes

243.82 g \ of Fe_2S_3

The outcome is 243.82 g of ferrous sulphite

By the above given formula we can find any amount of Fes produced by any amount of  ferrous react with sulphite.

Why doesn't peppermint improve your reaction?
skelet666 [1.2K]
The myth that peppermint makes you smarter, is false, but there are benefits to the scent of peppermint. Although, eating peppermint flavored candies is not as beneficial as actually smelling the peppermint before the test.

Peppermint in many forms such as tea, candy, and oil can be used to help improve mental awareness. The menthol “stimulates the Hippocampus area of the brain which controls mental clarity and memory. The odor triggers you to wake up and pay attention.” This explains why many people believe that peppermint makes you smarter, when really it makes you more alert.

Peppermint also has the ability to improve athletic performance as well as helping to improve reaction times.

Overall, peppermint can improve your mental awareness but, no, it does not actually make you smarter.
