Sanna and Eddie are getting breakfast at a coffee shop. Sanna bought a chocolate donut, and Eddie bought an apple fritter. Both Sanna and Eddie want to try the other person’s donut. Metaphorically speaking, if donuts were valence electrons, describe in terms of non-polar covalent, polar covalent, and ionic interactions how the donuts will be shared between Sanna and Eddie. And prt 2
What if Sanna eats her entire chocolate donut, and Eddie eats his entire apple fritter?
Predict the type of interaction:

Select one:
a. No bond is formed.
b. This is a metaphor for an ionic bond.
c. This is a metaphor for a perfectly non-polar bond.
d. This is a metaphor for a nuclear reaction.

first, consult an activity series chart to determine if al is more reactive than fe. it is, so it will replace the fe. now, one can continue with the problem.

next, make sure you have a correctly balanced equation.

3feo + 2al ==> 3fe + al2o3

now, determine which reactant (feo or al) is in limiting supply.

moles feo present = 125 g x 1 mole/71.8 g = 1.74 moles

moles al present = 25.0 g x 1 mole/26.98 g = 0.927 moles

since from the balanced equation, it take 3 mol feo for every 2 mol al, al will be limiting.

you can determine this simply by dividing moles of each by their coefficient in the balanced equation. for example: 1.74/3 = 0.58 and 0.927/2 = 0.464. al is less, so it is limiting.

finally, using the stoichiometry in the balanced eq. determine mass of fe that can be produced from 0.927 moles of al.

0.927 moles al x 3 moles fe/2 moles al x 55.8 g/mole = 77.6 g

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.
