I think you would immediately recognize that you had been short-changed.

Now looking at the equation,

$2Al + 3O_2 rarr 2Al_2O_3$,

on each side there are 6 oxygen atoms, but on the left hand side there are 2 aluminum atoms, and on the RHS, there are 4 aluminium atoms. And this the equation is UNBALANCED, and thus it CANNOT be accepted as a representation of chemical reality.

The stoichiometrically balanced equation has GARBAGE OUT EQUIVALENT TO GARBAGE IN..........i.e.

$4Al+3O_2 rarr 2Al_2O_3$

On the other hand, if you were presented with $2+4=10$, would you twig that the balance is shot?

A chemical compound requires 8 ounces of Chemical A and 12 ounces of Chemical B. A mixture contains 24 ounces of Chemical A and 30 ounces of Chemical B. How can you fix the mixture to make the chemical compound?

Since 8x3=24 and since 12x3=36 you need to add 6oz of chemical B to have 24oz of chemical A and 36oz of chemical B. Take 1/3 of the total mixture...

2Al+Zn(NO3)2=2Al(NO3)3+Zn net ionic equation?

The equation given above is wrongly balanced, so I have to correct it first. $Al^@$ + $Zn(NO_3)_2$ = $Al(NO_3)_3$ + $Zn^@$ (unbalanced) Tallying the atoms based on subscripts, left side:...

Which equation is correctly balanced: $A.$ $Al(s) + 3O_2(g) rarr Al_2O_3(s);$ $B.$ $Al(s) + 3O_2(g) rarr Al_2O_3(s);$ $C.$ $Al(s) + 3/2O_2(g) rarr Al_2O_3(s);$ $D.$ $2Al(s) + 3O_2(g) rarr 2Al_2O_3(s)?$

Alumina is $Al_2O_3$, which is the product of aluminum oxidation. None of your equations shows the correct formulae. We can rewrite the correct equation as: $2Al(s)+ 3/2O_2(g) rarr Al_2O_3(s)$ This...

The following chemical equation is not balanced: $Fe_2O_3 + H_2SO_4 -> Fe_2(SO_4)_3 + H_2O$. When this chemical equation is correctly balanced, what is the coefficient of the water molecule?

Water has a $3$ coeeficient. Is the equation stoichiometrically balanced? If not, then it should be. The oxide ion is dibasic, and reacts with 2 equiv $H^+$ to give the...

Is this equation $2Al + 3NiB _ { 2} -> AlB r _ { 3} + 3N _ { i }$ balanced?

No. A balanced equation displays an equal amount of atoms of each element on both sides of the yield arrow. From what you gave us/me, there are:...

Using the reaction, $4Al + 3O_2 -> 2Al_2O_3$, how do you identify the limiting reactant in each of the following: 0.25 mol Al and .40mol $O_2$ and 58.5g Al and 98.0g $O_2$?

The limiting reactant is the reactant that is present in less amount. 4 mol of Al need to react completely of 3 mol of Oxygen (according with the reaction you...
