Question

Is the chemical equation 4al + 2o2 > 2al2o3 balanced

Answer 1

No equation is not balanced,

`4Al+ 2O_(2) \ \textgreater \ 2Al_(2)O_(3)`
Right now this is your equation.
in the first part or the part of the reactants we have 4 Al and on the product we have also 4 but in O in the reactants there are 4 but there are 6 on the products.
For the equation to be balanced it should be:

`4Al+ 3O_(2) \ \textgreater \ 2Al_(2)O_(3)`
