Answer:
3Mg +Fe2O3 ---> 3 MgO + 2Fe
Explanation:
3Mg +Fe2O3 ---> 3 MgO + 2Fe
Mg 3 Mg 3
Fe 2 Fe 2
O 3 O 3
before after
Answer:
3Mg + Fe2O3 = 2Fe + 3MgO
Explanation:
Make sure the number of each element equal on both right and left hand side
Eg. There are 3 molecules of oxygen on left hand side so to balance right hand side add a 3 in front of MgO, because you've added a 3 in front of MgO you now have to add a 3 in front of Mg on the left hand side to balance it out and continue to do so for the rest of the chemical equation.
