The table compares the features of two plant species that exist near the shoreline in South Florida. Tree Species Data Tree Species Shade Provided Native Low Exotic High The nesting sites of sea turtles are more successful when the sites have more sunlight and warmer temperatures. Using the information from the table, predict how the type of tree species at the nesting site would impact the sea turtle population. (3 points) If there are more exotic species then the sea turtle population will increase. If there are fewer native species then the sea turtle population will increase. If there are fewer exotic species then the sea turtle population will increase. If there are more native species then the sea turtle population will decrease.

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
