Protons and neutrons are found in the nucleus . They group in the center of the atom
The three subatomic particles are protons, electrons, and neutrons. Protons and Neutrons are found in the nucleus of the atom. The electrons are found in a cloud that is orbiting all around the nucleus.
The neutron is found in the nucleus
The electron is found outside the nucleus
The proton is found in the nucleus
neutron and proton in the nucleus
electron in the electron cloud
The neutron is neutral
Proton is positive
Electron is negative
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
