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...

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...

Is the following chemical equation balanced? $2Al + 30_2 -> 2Al_2O_3$?
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...

What type of chemical reaction is $4Fe + 3O_2 -> 2Fe_2O_3$?
Zerovalent iron is oxidized to give $Fe(II^+)$. Zerovalent oxygen is reduced from $0$ to $-II$. Each year significant amounts of money are spent to prevent the corrosion of structural steel....

What type of reaction is $4Al + 3O_2 ->Al_2O$?
$4Al(s) + 3O_2(g) rarr 2Al_2O_3(g)$ This is a redox reaction, and represents the oxidation of aluminum metal by dioxygen gas to give alumina.

A chemistry has 14.5 g of Al and 7.5 g of $O_2$. What would the excess be for the following reaction: $4Al + 3O_2 -> 2Al_2O_3$?
To check excess and limiting reactants, the number of moles has to be found, and then divided by the coefficient. For the sake of shortening the equations, let us say...

What is the type of the reaction $4Al + 6HCl -> 2Al_2Cl_3 + 3H_2$?
Aluminum metal is oxidized to aluminum ion... $Al(s) rarr Al^(3+) +3e^-$ $(i)$ Hydrogen ion is REDUCED to dihydrogen... $H^+ +e^(-) rarr 1/2H_2(g)$ $(ii)$ We add $(i)+3xx(ii)$ $Al(s)+3H^+ +3e^(-) rarr Al^(3+)...

In the chemical reaction $4Fe+3O_2 -> 2Fe_2O_3$, which elements are oxidized?
And we could represent this by half-equations....CLEARLY iron metal is oxidized.... $FerarrFe^(3+) + 3e^(-)$ $(i)$ And meanwhile, the potent OXIDANT, dioxygen gas is reduced to $O^(2-)$... $O_2(g) + 4e^(-) rarr...

In the reaction represented by the equation $2Al_2O_3 -> 4Al + 3O_2$, what is the mole ratio of aluminum to oxygen?
As per the equation , $2$ moles of Aluminum Oxide ($Al_2O_3$) produces $4$ moles of Aluminum ($Al$) and $3$ moles of Oxygen ($O_2$). The ratio of $Al$ to $O$ is...

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...
