Question

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?

Answer 1

4,3,2

Step-by-step explanation:

Answer 2

The sequence of coefficient that should be placed in the blank space to balance ii as follows

the sequence is 2 infront of Al 3 infront of O2 and 2 infront of Al2O3

that is 2Al +3O2 = 2Al2O3

from equation above 2 moles of Al reacted with 3 moles of O2 to form 2 moles of Al2O3
