The formula for aluminum sulfate is $Al_2(SO_4)_3$. What is the molar mass of aluminum sulfate to the nearest gram?
The idea here is that the molar mass of aluminium sulfate, $"Al"_ 2("SO"_4)_color(blue)(3)$, will be equal to the sum of the molar masses of all the atoms that make up...

What is the formal charge on the sulfur atom in sulfur trioxide $SO_3$?
Sulfur assumes a $+VI$ oxidation state in the acid anhydride sulfur trioxide, and of course has the same oxidation state in sulfuric acid. $(O=)S^(2+)(-O^-)_2$ Most chemists would settle for...

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...

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...

How many moles of aluminum, sulfur, and oxygen atoms are there in 7.00 moles of aluminum sulfate, $Al_2(SO_4)_3$?
In one mole of aluminum sulfate, $"Al"_2"(SO"_4")"_3"$, there are 2 moles Al atoms, 3 moles sulfur atoms, and 12 moles O atoms. To determine the number of moles of atoms...

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...

According to the following reaction, how many moles of sulfur trioxide will be formed upon the complete reaction of 0.971 moles of sulfur dioxide with excess oxygen gas? sulfer dioxide (g) + oxygen (g) $->$ sulfer trioxide
We need a stoichiometic equation: $SO_2(g) + 1/2O_2(g) rarr SO_3(g)$ The equation unequivocally tells us that the reaction of $64*g$ $SO_2(g)$ with $16*g$ $O_2(g)$ gives $80*g$ $SO_3(g)$. The given masses...

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...

Can you assign the sulfur oxidation states in $"sulfate ion,"$ $SO_4^(2-)$, and $"sulfite ion,"$ $SO_3^(2-)$?
.......These differ by oxidation state. $SO_4^(2-)$ exhibits a $S(+VI)$ oxidation state. $SO_3^(2-)$ exhibits a $S(+IV)$ oxidation state. Of course, you can see the difference in the number of oxygen atoms...

Which acid and which base would you combine to form the salt aluminum sulfate, $Al_2(SO_4)_3$?
From the product you need an Al ion and the sulfate ion. The most likely source for the sulfate would be sulfuric acid. The base most readily available would be...
