How is cloning different from hybridization?

1. Hybridization is a method of sexual reproduction whereas cloning is a method of asexual reproduction.

2. Hybrid animals are sterile, but cloned animals are fertile.

3. Hybrid organisms contain DNA from both male and female parents but cloned organisms contain DNA from only one type of parent.

4. Hybrid has superior character over its parents (improved hybrid vigor) but clones are 100% identical to their parent.

5. Hybridization gives only one hybrid progeny, whereas through cloning unlimited identical organisms can be produced.

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
