Consider the unbalanced equation for the oxidation of aluminum. _al + _o2 mc031-1.jpg _al2o3 which sequence of coefficients should be placed in the blanks to balance this equation?

The options are
2, 3, 1
1, 3, 2
4, 3, 2
3, 2, 3

when balancing equation the masses should be balanced. In other words the same number of atoms of the same element should be on either side of the equation

the balanced equation for the oxidation of aluminium is as follows

4Al + 3O₂ ---> 2Al₂O₃
coefficients are the numbers in front of the respective compounds.
the coefficients in the correct sequence are 4,3 and 2

answer is 4, 3, 2
