Answer:
Percent yield = 90.8%
Explanation:
The reaction of Fe with S to produce FeS is:
Fe + S → FeS
<em>Where the moles of Fe added in excess of S are the moles of FeS</em>
<em />
Now, percent yield is defined as 100 times the ratio between actual yield (13.8g of FeS) and theoretical yield (15.2g FeS):
Percent yield = 13.8g / 15.2g * 100
<h3>Percent yield = 90.8%</h3>

Easy (:
C₃H₈ (g) + O₂ (g) ---> CO₂ (g) + H₂O
1 C₃H₈ (g) + 5 O₂ (g) ---> 3 CO₂ (g) + 4 H₂O
With this there is the same amount of elements on each side (You take the larger number in front and multiply it by whats after it. So you have 3 C, 8 H, and 10 O on one side, and then the next mirrors is with 3 C, 8 H, and 10 O.
A) a symbol showing that it is poisonous
b) gloves and other bodily protection
c) a symbol showing that it is flammable
d) they most likely were unaware. I do not think they would intentionally hurt people.
