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...

7.0 moles of sulfur atoms and 10 moles of oxygen molecules are combined to form the maximum amount of sulfur trioxide, how many moles of which reactant remain unused at the end of the reaction?
.........And oxygen is in deficiency. Given $10$ $mol$ of dioxygen gas, at most, $6.67$ $mol$ of sulfur trioxide can be generated. This is clearly indicated by the stoichometric equation. Should...

If sulfur dioxide and oxygen can be made into sulfur trioxide, what is the reverse reaction?
Vast quantities of $"sulfur trioxide"$ are utilized industrially for sulfuric acid synthesis: $SO_3 + H_2Orightleftharpoons H_2SO_4$

The atomic number of sulfur is 16. Sulfur combines with hydrogen by covalent bonding to form a compound, hydrogen sulfide. Based on the number of valence electrons in a sulfur atom, how do you predict the molecular formula of the compound?
We thus predict that hydrogen sulfide would have a formula of $H_2S$, an analogue of the popular $H_2O$ molecule.

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...

What volume of $O_2$ (g) at $350^oC$ and a pressure of 5.25 atm is needed to completely convert 5.00 g of sulfur to sulfur trioxide?
We can combine the given equations........ $S(s) + 3/2O_2(g) rarr SO_3(g)$ And this clearly gives us the mass transfer; 1 equiv of sulfur is oxidized by 3/2 equiv dioxygen gas........

What volume of $O_2(g)$ at 350. $"^o$C and a pressure of 5.25 atm is needed to completely convert 10.0 g of sulfur to sulfur trioxide?
$"Moles of sulfur"$ $=$ $(10.0*g)/(32.06*g*mol^-1)=0.312*mol$. Given the , we require $3/2xx0.312*mol$ of dioxygen gas, i.e. $0.468*mol$. And now we solve for volume in the Ideal Gas equation: $V=(nRT)/P$ $=$ $(0.468*cancel(mol)xx0.0821*L*cancel(atm)*cancel(K^-1)*cancel(mol^-1)xx623*cancel(K))/(5.25*cancel(atm))$...

If a reaction of sulfur dioxide with dioxygen gas to form sulfur trioxide starts with $"5 mols SO"_2$ and $"5 mols O"_2$, and $60%$ of the $"SO"_2$ was consumed in the reaction, what is the total mols of gas at equilibrium?
$"8.5 mols of gas"$ Write the reaction: $2"SO"_2(g) + "O"_2(g) -> 2"SO"_3(g)$ For this reaction, you know that the starting mols are: $n_("SO"_2,i) = "5 mols...
