Question

in the equation 2 al2o3 --> 4 al + 3 o2, what is the mole ratio of aluminum to oxygen? 2:3 10:6 3:4 4:3

Explanation:

Step1: Identify the coefficients

In the chemical equation \(2Al_2O_3
ightarrow4Al + 3O_2\), the coefficient of \(Al\) is \(4\) and the coefficient of \(O_2\) is \(3\).

Step2: Determine the mole ratio

The mole ratio of aluminum (\(Al\)) to oxygen (\(O_2\)) is based on their coefficients. So the ratio is \(4:3\).

Answer:

\(4:3\)
