One mole of iron III sulfate, $Fe_2(SO_4)_3$, contains how many moles of $SO_4^-2$ ions? How many moles of O atoms?
Here, we use as we would use any other collective number: a dozen eggs; a Bakers' dozen; a Botany Bay dozen. Of course, the mole specifies a much larger quantity,...

You are given quantities of aluminum sulfate, $Al_2(SO_4)_3$, and sulfuric acid, $H_2SO_4$. If there are EQUAL numbers of SULFUR atoms with respect to each salt, what is the ratio of oxygen atoms...$Al_2(SO_4)_3:H_2SO_4$?
It is given that both salts contain the same number of sulfur atoms. Thus we have $Al_2S_3O_12$, and necessarily $3$ $xx$ $H_2SO_4$. There are $3$ $"equiv"$ sulfuric acid per equiv...

The energy required to ionize sodium is 496 kJ /mol. What minimum frequency of light is required to ionize sodium?
Your strategy here will be to use Avogadro's number to find the energy needed to ionize one atom of sodium use the Planck - Einstein...

How do you balance the equation: $(A)FeSO_4+(B)KMnO+(C)H_2SO_4 -> (D)Fe_2(SO_4)_3+(E)K_2SO_4+(F)MnSO_4+(G)H_2O$ ?
Let's eliminate unknowns backwards, starting with $G$. From the equations for $H$, $Mn$, $K$ and $Fe$ we find: $G=C$ $F=B$ $E=1/2 B$ $D=1/2 A$ Substituting these in the...

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...

How do you balance $Fe+H_2SO_4 -> Fe_2(SO_4)_3 + H_2$?
Start by looking at the most complex compound, and balancing around that. In this case, its $Fe_2(SO_4)_(3(aq))$. We see that we need 2 Fe and 3 $SO_4$ on the...

When 7.25 g of $Al$ reacts with excess $H_2SO_4$ in the reaction $2Al (s) + 3 H_2SO_4 (aq) -> Al_2(SO_4)_3(aq) + 3H_2(g)$ how many liters of $H_2$ is formed at 25° C and a pressure of 1.650 atm?
$2$ $Al(s)$ + $3$ $H_2SO_4(aq) to $ $Al_2(SO_4)_3(aq)$ + $3$ $H_2(g)$ First calculate the number of moles of $Al$ in $7.25$ $g$, knowing the molar mass of $Al$ is $27$...

In the reaction $Al_2(SO_4)_3 + 6NaOH -> 2Al(OH)_3 + 3Na_2(SO_4)_3$, how many moles of $Al(OH)_3$ can be made with 2.3 moles of $NaOH$ and excess $Al_2(SO_4)3$?
Since aluminium sulphate is in excess, it implies that sodium hydroxide is the limiting reactant and decides how much product is formed as it gets used up first. The balanced...

Using the balanced equation $3Ba + Al2(SO_4)_3 -> 2Al + 3BaSO_4$, if 4g Ba react with 0.45 g $Al_2(SO_4)_3$, what is the excess reactant?
Balanced Equation $"3Ba + Al"_2"(SO"_4)_3"$$rarr$$"2Al + 3BaSO"_4$ The coefficients are the moles of each substance, and they can be used as molar ratios between two of the substances. No coefficient...

Define the terms theoretical yield, actual yield, and percent yield. Why is the actual yield in a reaction almost always less than the theoretical yield? Can a reaction ever have 110% actual yield?
Actual yield in a reaction is almost always less than the theoretical yield, primarily because losses of the substances involved may occur anywhere in an experiment. Otherwise, there can be...
