Balance the equation by putting the correct number in front of each compound. You can work this out mathematically or by drawing pictures on a piece of paper like the videos. Al + 02--> Al203 corrosion of aluminum

4Al + 3O₂ —> 2Al₂O₃

The coefficients are: 4, 3, 2

Explanation:

__ Al + __ O₂ —> __ Al₂O₃

The above equation can be balance as illustrated below:

Al + O₂ —> Al₂O₃

There are 2 atoms of O on the left side and 3 atoms on the right side. It can be balance by writing 3 before O₂ and 2 before Al₂O₃ as shown below:

Al + 3O₂ —> 2Al₂O₃

There are 4 atoms of Al on the right side and 1 atom on the left side. It can be balance by writing 4 before Al as shown below:

4Al + 3O₂ —> 2Al₂O₃

Now the equation is balanced.

The coefficients are: 4, 3, 2

organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.
